A three-gene data set was generated to explore species diversity and delimitations within the stalked puffballs (Tulostoma, Agaricales) in Europe. Data on species from other parts of the world were included for comparison of species concepts and distribution ranges. Sequence data from 26 type specimens are included. The phylogenetic analyses support Tulostoma as monophyletic. Eleven major clades, 37 minor clades, and 20 single branches were recovered and found to correspond to 30 described species and 27 species without scientific names.

Five species are here described as new to science: Tulostoma calcareum, T. calongei, T. eckbladii, T. grandisporum, and T. pannonicum. In total we report 26 described, and 19 undescribed, species from Europe. An epitype for T. fimbriatum with ITS sequence data is selected to fix the name.

The recovered tree topology was not in congruence with the current infrageneric classification of Tulostoma, suggesting that many of the morphological characters used for segregation of taxa are plesiomorphic or homoplasious. Spore ornamentation and hyphal structure of the peridium are found to be reliable characters for delimitation of species.

The majority of the species occur in the dry, arid areas of southern and east central Europe but a few are shown to be restricted to humid temperate regions in the North. The study confirms that species with smooth or sub-smooth spores are restricted to dry and arid habitats whereas species with more strongly ornamented spores occur in humid habitats.

Areas with steppe vegetation in Hungary and Spain are here identified as hot spots for Tulostoma species diversity.

The genus Tulostoma Pers. : Pers. was erected by Persoon (1794, 1801) to accommodate puffball species with a “peridium pedicellatum”, opening with an “ore cylindraceo cartilagineo”. Persoon included two species in the genus, T. brumale and T. squamosum. The former had previously been illustrated by Tournefort (1700) as Lycoperdon parisiense and later described by Linnaeus (1753) as Lycoperdon pedunculatum. Fries (1829) mentioned four species, viz. T. mammosum (including T. squamosum), T. fimbriatum, T. tortuosum and T. laceratum (=Schizostoma lacerata). However, in a later work, Fries (1849) replaced Tulostoma with Tulasnodea, honouring the Tulasne brothers, contemporary mycologists based in Paris. However, according to the rules of nomenclature, Tulostoma must be considered the correct name for this characteristic genus, being sanctioned by Persoon (1801). An orthographic variant, Tylostoma, is sometimes seen in older literature. Early contributions to the knowledge of Tulostoma are the works of Bottomley (1948), Coker and Couch (1928), Cunningham (1925, 1932), Hollós (1904, 1913), Lloyd (1906), Long (1944, 1946), Long and Ahmad (1947), Morgan (1891), Petri (1904, 1909), Pouzar (1958), Shvartsman and Filimonova (1970), Smith (1951), and White (1901).

Schroeter (1876) studied young and old basidiomata of Tulostoma and described the development of the basidiomata, in particular basidia and capillitium. Later Wright (1955) surveyed important morphological characters in the genus. This was followed by the world monograph of Tulostoma (Wright 1987), where he accepted 139 species. Wright’s species concept was largely based on type studies and studies of numerous additional herbarium specimens. With the introduction of scanning electron microscopy (SEM), detailed spore morphology could be used as a base for taxonomic rearrangements and introduction of new species (Altés and Moreno 1995, Altés and Moreno 1999, Altés et al. 1999, Moreno et al. 1992a, Moreno et al. 1997).

From the late 20th century the arid regions of Mexico have been intensely explored with regard to Tulostoma (Esqueda et al. 2004, Hernández-Navarro et al. 2015, Moreno et al. 1995b, Piña et al. 2010, Wright et al. 1972). In addition, South America, particularly Brazil, has recently been subject to detailed studies on Tulostoma (e.g. Baseia and Milanez 2002, Cortez et al. 2009, Silva et al. 2007). Silva’s (2006) thesis on Tulostoma substantially increased the knowledge of the genus in Brazil. For South Africa, Coetzee (2007) published a key to the known taxa and Moreno et al. (1995a), Moreno et al. 2002, and Kreisel and Scholler (2008) added species for the continent. For Asia, Liu (1979), Asai (2004), Asai and Asai (2008), Dörfelt and Bumžaa (1986), Hussain et al. (2016), Sesli et al. (2000), and others have published survey reports on the occurrence of the genus. In Europe, numerous papers dealing with the genus have been published: Altés et al. (1996), Antonín and Kreisel (2008), Calonge (1992, 1998), Calonge et al. (2007), Calonge and Martín (1992), Jeppson (2006a,b, 2008), Kreisel (2004), Kříž (2011), Martín (1990), Martín and Calonge (1994), Moreno et al. (1990), Mrazek et al. (1995), Sarasini (2003, 2005), Schubert and Specht (2013a,b), Specht and Schubert (2012), Specht et al. (2016), and Tomaszewska et al. (2011).

The introduction of molecular data has led to major changes in fungal systematics and taxonomy. Hibbett et al. (1997) were the first to show that the puffball genus Tulostoma belongs in Agaricales. Although the genus has been intensively studied from a morphological point of view, so far comparatively few molecular phylogenetic studies with a focus on Tulostoma have been published, and these are mainly geographically restricted and deal with a low number of species (cfr. Hernández-Caffot et al. 2011, Hussain et al. 2016).

In the present study we use a three-gene phylogeny with the aim to explore species diversity and phylogenetic relationships within Tulostoma. The data set includes the ITS, LSU, and Tef-α regions of the majority of the European species. In addition, species described from other parts of the world are included for comparison of species concepts and distribution ranges. Retrieval of ITS sequence data from type and other herbarium specimens was attempted when permission for sequencing was given and as the condition of the material allowed.

Material and methods

Morphological methods

The genus Tulostoma is easy to identify to genus level in the field. Precise determination to species level is, however, often difficult, because the characters used are few in number and subtle in nature. According to Index Fungorum (; accessed July 1, 2016) there are well over a hundred Tulostoma names to consider, many of them known from old and scanty type materials at best. Our sampling and selection of species was compiled through field studies and collecting in various parts of Europe during the last 25 years (collections stored in GB and AH).

Additional collections and type specimens were studied as loans from herbaria around the world (BPI, BRA, C, FH, L, LD, LISU, MA, NY, O, PC, PRM, S, TRH, and UPS). Herbarium acronyms are in accordance with Index Herbariorum ( Species very recently recorded from Europe (T. bruchi, T. leslei, T. palatinum, and T. vulgare) are not included in this study (Antonín and Kreisel 2008, Calonge 1992, 1998, Specht et al. 2016).

Collections were mostly photographed in situ, dried, and later studied in the laboratory under a stereo-microscope. Morphological features are named in accordance with Wright (1987). For microscopic studies, samples of mature gleba were mounted in Cotton blue + lactophenol and heated to boiling. Features of the peridium were studied in Melzer’s reagent. A light microscope equipped with a Dino-Eye Eyepiece Camera was used for studies of micro-morphological characters. Spores were measured at a magnification of 1000x, using the Dino-Lite 2.0 software ( . A minimum of 20 spores were measured for each sample. All spore measurements are given excluding ornamentation. Studies under SEM were conducted according to the procedure of Moreno et al. (1995b).

Molecular methods

Taxon sampling

For this study, 183 ingroup specimens were sequenced, including the type specimen of 24 species. ITS sequence data of the type specimens of T. domingueziae (HQ667597) and T. ahmadii (KP738712) were taken from GenBank (Hernández-Caffot et al. 2011, Clark et al. 2016). Specimens were selected with the aim to cover all the species known to occur in Europe and from a broad geographic distribution within the area. In addition, specimens from North America and Central Asia were included for comparison of species concepts and distribution ranges. The sequenced specimens shown in Figure 1a–c are indicated with an asterisk in the lists of specimens examined and are listed with GenBank accession numbers as Suppl. material 1.

Bootstrap values and Bayesian Posterior Probabilities are indicated on branches. The major clades (1-11) are marked with a scale bar. The clades represent species or species groups that are discussed in more detail in the text.

Three additional ITS and LSU sequences from Hernández-Caffot et al. (2011) were retrieved from GenBank and included in the data set (HQ667594, HQ667598-HQ667599). Based on results from earlier molecular phylogenetic studies of Agaricales (Hibbett et al. 1997, Matheny et al. 2006), Lycoperdaceae, Cyathus, Crucibulum, and Inocybe were selected as outgroup taxa.

DNA extraction, PCR, and sequencing

Sequence data from three genetic markers were generated for the study: the complete ITS region and about 1400 bases of the 5´end of the nuclear ribosomal LSU DNA, and about 1000 bases of translation elongation factor subunit 1 alpha (Tef-1a). DNA extractions were performed using DNeasy Plant Mini kit (Qiagen, Hilden, Germany), PCR reactions, and sequencing were performed as described in Larsson and Örstadius (2008). Primers used to amplify the complete ITS region and the 5´end of the LSU region were ITS1F (Gardes and Bruns 1993) and LR21, LR0R, and LR7 (Hopple and Vilgalys 1999). For Tef-1a we used EF983F and EF2218R (Rehner and Buckley 2005). Primers used for sequencing were ITS1, ITS4 (White et al. 1990), LR0R, LR5, and LR3R (Hopple and Vilgalys 1999, Tedersoo et al. 2015), EF983F, and EF2218R. Type specimens were extracted using a modified CTAB method, and PCR and sequencing followed protocols described in Larsson and Jacobsson (2004).

Phylogenetic analyses

Sequences were edited and assembled using Sequencher 5.1 (Gene Codes, Ann Arbor). Alignment of individual genes was performed using the L-INS-i strategy as implemented in MAFFT v. 7.299 (Katoh and Standley 2013). The alignments were adjusted manually using AliView (Larsson 2014). Sequences generated for this study have been deposited in GenBank (ITS/LSU: KC333055KC333076, KU518952KU519107, KX513825KX513827, KX576541KX576549, KX583648, KX640979-KX640988; Tef-1(: KU843875KU844001).

Separate phylogenetic analysis was done for all three genetic markers to test for overall congruity of the phylogenetic signal. The trees were found to be compatible with respect to the overall clades (results not shown), and the three genetic markers were concatenetad for the final analyses. Heuristic searches for the most parsimonious trees were performed using PAUP*. All transformations were considered unordered and equally weighted. Variable regions with ambiguous alignment, mainly from the ITS region, were excluded, and gaps were treated as missing data. Heuristic searches were performed with 1,000 random-addition sequence replicates, TBR branch swapping, and the MulTrees option in effect. Relative robustness of clades was assessed by the bootstrap method using 1,000 heuristic search replicates with 100 random taxon addition sequence replicates and TBR branch swapping, the latter saving at most 25 trees in each replicate.

Bayesian phylogenetic analyses were carried out in MrBayes 3.2.6 (Ronquist et al. 2012), with a best-fit model of nucleotide evolution for the separate gene partitions supplied by MrModeltest 2.2 (Nylander 2004). Eight default-setting Metropolis-Coupled Markov Chain Monte Carlo (MCMCMC) chains were run for 10 million generations with trees sampled every 5,000 generations and an initial burn-in of 50%. After discarding the trees prior to the burn-in threshold, a 50% majority-rule consensus phylogram was computed from the remaining 1,000 trees.


Molecular analysis

The aligned complete dataset, including sequences downloaded from GenBank, consisted of 198 taxa and 3,340 characters. After exclusion of ambiguous regions, mainly from the ITS1 and ITS2, 3,005 characters remained for the analysis. Of these, 1,992 were constant, 226 were variable but parsimony uninformative, and 787 (26%) were parsimony informative.

The maximum parsimony analysis yielded 3625 equally parsimonious trees (length=3,726 steps, CI= 0.3814, and RI= 0.8228). One of the trees is presented as a phylogram in Figure 1a–c.

The bootstrap analysis recovered Tulostoma as monophyletic with 95 % bootstrap support (BS). Thirty-seven minor clades and 20 single branches were recovered, corresponding to 30 described species and 27 without a scientific name. Five of these clades are here described as new species to science. Eleven major clades, ranging from virtually unsupported to having strong support, within the ingroup are recognized and named as Clades 1-11 in the phylogenetic tree (Figure 1a–c). These clades are further described and discussed below.

As suggested by MrModeltest, the nucleotide evolution model HKY+G was used for the ITS1 spacer; SYM was used for the 5.8S gene; HKY+G was used for the ITS2 spacer, and GTR+I+G were used for the nLSU and TEF genes in the Bayesian analysis. The MCMC analysis converged well in advance of the burn-in threshold and chain mixing was found to be satisfactory, as assessed by using Tracer v1.5 (Drummond et al. 2012). Also in the Bayesian analysis, Tulostoma was recovered as monophyletic with strong support (a Bayesian posterior probability (BPP) of 1.00). The Bayesian tree topology is similar to the MP bootstrap tree. The same clades and single branches recovered in the maximum parsimony analysis were also recovered in the Bayesian analysis, with the minor differences that several clades with low or no bootstrap support received a moderate to high BPP value. BPP values are indicated on the corresponding branches in Figure 1a–c.

None of the newly generated ITS sequences were significantly similar to the “most wanted fungi” ITS dataset of Nilsson et al. (2016) as explored through BLAST.

Comments on the major clades

Clade 1 (100, 1.0) includes only one species, T. punctatum. The exoperidium is hyphal and the mouth is fibrillose-fimbriate. It is similar to T. fimbriatum in macro-morphology but has smaller and more coarsely ornamented spores without anastomosing ridges. The species was treated as a variety of T. fimbriatum by Wright (1987).

Clade 2 (unsupported) includes four species that all have a hyphal exoperidium. Two of the species (sp.1, sp. 2) are unidentified. The specimens of these originate from halophytic vegetation in Spain and sand steppe vegetation in Hungary, respectively. Both have a fibrillose-fimbriate mouth, thus inviting comparison to the widespread T. fimbriatum in morphology. Tulostoma cyclophorum has a typically fibrillose-fimbriate mammose mouth but differs from other European species of Tulostoma by having abundant mycosclereids, i.e. rounded to elongated cells on the endoperidial surface, and subreticulate spores. Tulostoma obesum has a smooth endoperidial surface that lacks mycosclereids and the spores are completely smooth.

Clade 3 (90, 1.0) includes four species with similar morphology. They all have a hyphal exoperidium, fibrillose-fimbriate mouth and rather stout basidiomata, features that are characteristic of T. fimbriatum. An ITS sequence from the lectotype of T. campestre (=T. fimbriatum var. campestre) was generated and forms a monophyletic clade with the sequences of T. fimbriatum sensu stricto. As the morphology also is in congruence, we regard it as a synonym. An epitype is selected for T. fimbriatum (see taxonomy section) from the same district in Sweden as the holotype to fix the name also by ITS sequence data (Nilsson et al. 2012, Ariyawansa et al. 2014). Tulostoma winterhoffii, a recently described species from Germany, is identical with the ITS sequence from the holotype of T. fimbriatum var. heterosporum, and thus replaces that name. We describe a new species from Spain, T. calongei. It is similar to T. fimbriatum in habit but differs in spore morphology and molecular data. The unidentified T. sp. 3, also with the habit of T. fimbriatum, collected in Hungary, indicates the occurrence of cryptic speciation within this morphologically similar group. Although having been considered synonymous with T. fimbriatum or mere varieties of it (Altés and Moreno 1995, Wright 1987), ITS data (not shown in the tree) of type materials of the extra-European taxa T. egranulosum, T. readeri, and T. tuberculatum indicate them to be distinct species. The T. fimbriatum complex is in need of further studies.

Clade 4 (unsupported) includes two unidentified species (Tulostoma spp. 4 and 5) collected in sandy habitats in Central Europe. Tulostoma sp. 4 is fairly similar to T. fimbriatum in habit. Tulostoma sp. 5 has a circular, tubularly protruding mouth, a hyphal exoperidium, and irregularly ornamented, verrucose-echinate spores. The two species are very different morphologically and their placements in the tree are ambiguous and without significant support.

Clade 5 (-, .73) is an unsupported clade including 11 species. The holotype of T. lusitanicum (Figure 12), a species recently (2000) described from Portugal, is placed on a single branch basal in the clade, but without significant support. However, the residual subclades form a moderately supported clade (78/.99, Figure 1b). ITS sequence data of the holotypes of T. kotlabae, T. lysocephalum (from North America), and T. lusitanicum were included, but still we have eight unidentified clades (Tulostoma spp. 6-13). This indicates a high and previously unrecognized species diversity within the group, including cryptic speciation. The clade is in need of further study, and the addition of more sequence data appear to be needed to resolve the phylogenetic relationships. Tulostoma kotlabae and spp. 6-13 share morphological characters such as the circular, more or less tubularly protruding mouth, a hyphal exoperidium, pale colours of the basidiomata, and weakly to moderately ornamented spores. Tulostoma sp. 12 is known only from the Mediterranean area, and an Italian finding (AH 16793) was published as T. kotlabae by Altés et al. (1994). Tulostoma lysocephalum differs by having a fibrillose-fimbriate mouth (Figure 22).

Clade 6 (95, 1.0) includes five species. Tulostoma aff. cretaceum forms a strongly supported clade that comprises specimens from Russia, Hungary, and Spain. In morphology they are characterized by stout basidiomata with pale colours and a hyphal or slightly membraneous exoperidium, a very dark, chocolate brown colour of the mature gleba, an indistinct, irregular mouth that with age becomes lacerate, combined with totally smooth spores. However, as there is substantial sequence variation that correlates with geographic distribution within the clade (Russia, Hungary and Spain, respectively), it must be regarded as a complex of species. More data such as the sequence of the type of T. cretaceum are needed to resolve species delimitation within the Tulostoma aff. cretaceum clade. Sequence data from the holotype of T. macrocephalum from North America show this species to be closely related to Tulostoma sp. 14, which includes two specimens from Spain, collected in a halophytic habitat. Both species have a hyphal exoperidium but differ in basidiomata size and spore wall ornamentation. Tulostoma pseudopulchellum, a species characterized by a membranous exoperidium, a fibrillose-fimbriate mouth, and finely and irregularly ornamented spores comes out as a sister clade with strong support to what we describe as a new species (T. pannonicum, see taxonomy section). The new species is recognized by having small smooth spores and has previously been reported from Hungary as T. leiosporum (cfr. Jeppson et al. 2011, Rimóczi et al. 2011).

Clade 7 (86, .98) includes two species. Tulostoma submembranaceum was described from Mexico by Moreno et al. (1995b). The exoperidium is thinly membranous-verrucose, the mouth is fibrillose-fimbriate, and the spores have low verrucae that have a tendency to form crests. Tulostoma sp. 15 from Hungary and Spain, more or less matches the macro-morphology of T. submembranaceum but differs in spore ornamentation (irregularly rugulose) and molecular data.

Clade 8 (54, .85) includes four species. Uniting morphological characters are the presence of a fimbriate-fibrillose mouth and totally smooth spores. Two well-known species are T. fulvellum and T. lloydii. One of the recovered clades represents a species with large spores, characteristic of sandy habitats of East Central Europe. It is proposed as a new species (T. grandisporum, see taxonomy section). Tulostoma sp. 16 is a specimen from Siberia that in macro-morphology is similar to the newly described T. grandisporum but has significantly smaller spores. Both have irregular, undulating, or ragged inner walls of the capillitium. This striking character is also present in the lectotype of T. leiosporum, from which we were not able to obtain sequence data.

Clade 9 (100, 1.0) includes T. pulchellum and T. striatum and corresponds to section Poculata Pouzar & Moravec. The exoperidium is distinctly membranous, detaching in flakes. The endoperidium is white, velvety in young specimens, and has a mammose, fibrillose-fimbriate mouth that sometimes is surrounded by a more or less delimited peristome. They share macro-morphological features but can be readily separated by their spores that are finely asperulate in T. pulchellum and distinctly striate in T. striatum.

Clade 10 (69, -) includes 14 species. All species in this clade have a mouth that is circular and more or less tubular, or conically protruding. The spores are moderately ornamented. Tulostoma simulans, a species described from N. America, is according to our results widely distributed also in Europe. In some parts of Europe, T. simulans has been mistaken for T. beccarianum and the species T. moravecii. The latter now appears to be a later synonym. The well-known and widely distributed T. brumale is closely related, but clearly distinct from T. simulans, both in molecular and morphological data. Tulostoma beccarianum is a rare species described from Italy by Bresadola, but with recent records from Spain and East Central Europe. Tulostoma spp. 17-21, all represented by few specimens, are similar in morphology to T. beccarianum and T. simulans, and represent un-named cryptic species that need further attention. The ITS of the types of T. albicans, T. excentricum, and T. xerophilum, three species from North America, were generated and included, but did not match with any of our unknown species, and the latter occurs on a single basal branch in Clade 10. Tulostoma giovanellae is mainly associated with sandy, and often halophytic, habitats in southern and central Europe. The sister clade to T. giovanellae represents a species from northernmost Scandinavia that we describe as a new species (T. eckbladii, see taxonomy section). Within the clade there are also T. sp. 21, an unidentified Spanish specimen, closely related to T. eckbladii, and the characteristic bryophilous T. niveum.

Clade 11 (95, 1.0) includes eight species that morphologically are characterized by having rather dark colours of the stipe, endoperidia with initially brownish colours, and moderately to strongly ornamented, verrucose-echinate spores. The widely distributed T. squamosum has a membranous-verrucose exoperidium of sphaerocysts, which upon maturity forms a dark reticulum on the brownish endoperidium. The closely related T. subsquamosum has a paler, hyphal exoperidium with only scattered sphaerocysts, and never forms a reticulum. It was described from India and reported from Spain by Altés et al. (1996) and is here confirmed also from East Central Europe (Hungary and Slovakia). Sequence data indicate a close relationship with the recently described T. ahmadii (Hussain et al. 2016). Tulostoma melanocyclum is a widely distributed species in Europe. The recently described T. domingueziae, reported from South America (Hernández-Caffot et al. 2011), as well as T. rufum (lectotype; North America) come out as sister species. One of the recovered clades is described as a new species (T. calcareum, see taxonomy section) that has a wide European distribution. The sequence data of T. sp. 22 represent an undescribed species from South America.

The holotype material of T. beccarianum, described in 1904, was sequenced in this study. Identical sequences were obtained from recently collected material from Hungary, Slovakia, and Spain. The species was given a detailed description by Altés and Moreno (1993) based on the holotype. The newly collected samples have rather large and stout basidiomata, spore-sacs measuring up to 22 mm in diameter, and a stem reaching 120 mm. The exoperidium is indistinct or hyphal, and the endoperidium is smooth, dirty white-greyish, with a circular, shortly raised mouth. The stem base is widened and forms a volva-like structure. The capillitial septa are slightly widened. The capillitium seems to break up easily at the septa, leaving segments with somewhat widened, rounded ends. The type material shows irregular, undulating inner walls of the capillitium, a character that is also noted in the recently collected material. The spores are irregularly verrucose, 4–5 µm, av. 4.5 µm, ornamentation excluded (Figure 2a) and agree with those of the holotype (4.7–6 µm, ornamentation included; Altés and Moreno 1993). The synonymisation of T. beccarianum with T. simulans, as proposed by Altés and Moreno (1993), was contradicted by the molecular analyses. The name T. beccarianum has apparently sometimes been misapplied for T. simulans (syn. T. moravecii). Tulostoma sp. 19 includes a single collection from Cyprus, with more or less identical morphology. It is currently treated as an undescribed species until more material becomes available.

Habitat and distribution

In semi-shaded to exposed localities in dry grasslands (Hungary and Slovakia) and halophytic vegetation on sand (Spain). Apparently a very rare species.

FRANCE, “circa Parisios” (L); several collections by Persoon available at L, but no type seems to have been formally designated (cfr. Wright 1987).

Tulostoma brumale is well characterized by its membranous exoperidium, the circular-tubular mouth –which is usually surrounded by a brown peristome – and its abrupt widenings of the capillitial septa. SEM-photos of the spores show an irregular ornamentation of blunt, broad-based verrucae (Figure 2b). It can be separated from T. simulans by the exoperidial features, its slightly smaller spores, and the presence of irregular crystals adhering to the capillitial walls.

Habitat and distribution

According to Wright (1987), T. brumale is recorded from N and S America and Asia (Georgia). Shvartsman and Filimonova (1970) reported it from Central Asia and Rebriev and Gorbunova (2007) added findings from Siberia. In Europe it is one of the more common species of Tulostoma, recorded north to 60° in Fennoscandia. It occurs in all types of sandy and calcareous grasslands, sand dunes, and sand steppe vegetation, as well as on moss covered rocks and stone walls. It is often associated with mosses, particularly Syntrichia spp.

Figure 3


Sweden, Södermanland, Mörkö, Egelsvik, Kalkberget, on calcareous soil under Artemisia campestris in rocky slope, 5 Nov. 2004, M. Jeppson 6965 (GB!, isotype AH).


The name refers to its habitat requirement, on calcareous sandy soil or among calcareous rocks and cliffs.


Spore-sac subglobose, often somewhat depressed, 5–12 mm. Exoperidium hyphal-verrucose, deciduous, sometimes persisting as whitish verrucae scattered on the endoperidial surface. Endoperidium brownish-ochraceous, initially rather dark coloured, with age fading to greyish white. Mouth circular, shortly tubular (Figure 3f), surrounded by a greyish or brownish peristome. Socket separated from the stem, inconspicuous. Stem slender, 20–50 x 2–3 mm, initially orange brown, with age warm reddish brown, longitudinally furrowed, smooth to fissured and appressed scaly, with a basal mycelial bulb (Figure 3a,e). Gleba ochraceous to ferrugineous brown. Capillitium 4–10 µm with medium-thick walls, sometimes abundantly ramified. Septa not or very slightly widened (Figure 3b). Spores subglobose, 4.0–6.0 µm (av. 4.7–5.0 µm), verrucose-echinate. SEM-photos show spines in groups with connected tips, sometimes coalescing to form ridges and crests (Figure 3g–i).

Habitat and distribution

Occurs in dry, exposed to semi-shaded situations in calcareous, sandy habitats and on calcareous rocks and cliffs. It is currently on record from Hungary, Norway, Spain, and Sweden.


Tulostoma calcareum was commonly misinterpreted as T. squamosum (cfr. Nitare 1997), under which name it is red-listed as Critically endangered (CR) in Sweden (Artdatabanken 2015). It differs from T. squamosum by having a hyphal to slightly verrucose exoperidium, by lacking sphaerocysts, and by never forming the reticulate pattern typical of T. squamosum. The stipe is also less squamulose. Spores and capillitial characters are almost identical. It differs from T. melanocyclum, with which it can easily be confused, by having a more robust stature, more orange-reddish brown colours of the stipe, and slightly smaller spores (av. 4.7–5.0 µm vs 5.2–5.4 µm in T. melanocyclum). SEM-photos of T. melanocyclum (Figure 2i) show similar spore ornamentation but with spines with less tendency to coalesce and form ridges. In macro-morphology T. calcareum is fairly similar to T. ferrugineum D.M. Oliver & Hosford, a species described from northwestern USA, whose type material no one has been able to locate (Wright 1987). However, according to its original description, it differs from T. calcareum by having distinctly widened capillitial septa.

Spain, Madrid, Casa de Campo, in exposed situation on dry sandy soil, S. Jeppson, J. Jeppson, M. Jeppson, 21 Nov. 1989, M. Jeppson 8773 (GB!, isotype AH).


Named in honour of the Spanish mycologist Francisco D. Calonge.


Spore-sac 8–10 mm, subglobose. Exoperidium granulose hyphal, encrusting soil, sometimes detaching in small flakes, whitish-greyish, rather persistent (Figure 4f). Endoperidium smooth, whitish. Mouth fimbriate. Stipe rather short, 15–20 x 1.5–2.5 mm, warm reddish brown, with darker appressed scales and a basal mycelial bulb (Figure 4f). Gleba ochraceous to ferrugineous brown. Capillitium 3–6 µm, thick-walled, with uneven inner walls (Figure 4c-d). Some ribbon-like hyphae present (Figure 4b). Septa rare, slightly widened. Spores globose-subglobose, 3.5–4.5 µm (av 4.1 µm) ornamentation excluded, verrucose-echinate, with spines frequently fused at their tips forming little developed pyramidal groups (Figure 4g-i).

Habitat and distribution

Tulostoma calongei has been collected only from central Spain, usually on sandy acidic soils.


Although usually having a less robust stature, this new species is very similar in macro-morphology to T. fimbriatum, with which it has been confused. The main differences are that the spores are slightly smaller and have a conical-pyramidal ornamentation, without the characteristic crests of T. fimbriatum (Figure 7c–e). The molecular data also clearly support them as distinct but closely related species, with T. calongei occuring as a sister clade to T. fimbriatum (Clade 3, Figure 1a). The distribution area for the species is likely to increase after reexamination of additional samples identified as T. fimbriatum from Meridional Europe.

Clade 6 in our study encompasses some closely related taxa previously attributed to T. volvulatum I.G. Borshch. and T. obesum Cooke & Ellis (cfr. Hollós 1904, Altés et al. 1999, Rimóczi et al. 2011). The main characteristics are the rather large basidiomata with hyphal exoperidium and almost pure white endoperidium with an indistinct to fibrillose-fimbriate mouth (or irregular scar) that with age becomes lacerate. The stipe base is provided with a volva and a prominent pseudorhiza. The spores are smooth and the capillitium is fragile, breaking up in segments with rounded ends. In our material this complex is represented by collections from Hungary, Russia (Altay Republic), and Spain. They are recovered as closely related and can be considered as cryptic species with a strong geographical signal. In morphology they fit the original description of the American species T. cretaceum fairly well. The Spanish collections deviate from the Hungarian specimens in having a stouter habit.

Habitats and distribution

Tulostoma cretaceum was originally described from New Mexico (USA) and later reported from Argentina (Wright 1987) and Baja California, Mexico (Moreno et al 1995b). There are recent records from Mexico (Sonora) and Brazil (Esqueda et al. 2004, Silva et al. 2007). In Europe T. aff. cretaceum is found in sand steppe vegetation in Central Hungary and in calcareous steppe habitats in Spain.

Tulostoma cyclophorum Lloyd, Mycol. Writings 7: 25. 1906.

Figure 2d


SOUTH AFRICA, Stoneman, herb. Lloyd 4495 (BPI).

Tulostoma cyclophorum is a morphologically characteristic species, originally described from South Africa, with a tomentose, white to ochraceous endoperidium covered with mycosclereids and a distinctly membranous exoperidium. The mouth is silky fibrillose-fimbriate. Its spores are unique among European Tulostoma lineages, being more or less reticulate (visible under SEM, Figure 2d; asperulate under light microscope).

Habitat and distribution

Mostly found in semi-shaded localities among grasses and herbs on lawns in city parks on somewhat sandy soil. From Europe currently reported from France, Italy, Hungary, and Spain (Demoulin 1984, Jeppson et al. 2011, Moreno et al. 1990, Sarasini 2005). It appears to have a cosmopolitan world distribution.

Figure 6


Norway, Nordland, Saltdal, Junkerdalsura, på sten blandt mos, 4 Sept. 1957, I. Jørstad (O F-58850!).


Named in honour of the Norwegian mycologist Finn-Egil Eckblad (1923-2000).


Spore-sac subglobose to onion-shaped, 6–8 mm in diameter. Exoperidium not observed. Endoperidium smooth, initially brownish, later ochraceous white. Mouth circular, shortly tubular, with a more or less brown peristome. Socket inconspicuous. Stem stout, 25–30 x 3–4 mm, flattened, light brown, somewhat longitudinally furrowed, almost smooth to finely appressed scaly, attenuated towards the base, with whitish basal rhizomorphs attached to moss rhizomes (Figure 6d). Mature gleba ochraceous-ferrugineous. Capillitium 4–6 µm with rather thick walls, with scattered septa that are slightly widened (Figure 6b). Spores subglobose, 4.5–5.5 µm (av. 4.9 µm) ornamentation excluded, coarsely but not very densely verrucose. SEM photos show isolated, irregular verrucae with broad bases (Figure 6e–g).

Habitat and distribution

Tulostoma eckbladii is so far only known from two findings in northern Norway, in both cases growing among mosses on calcareous boulders.


The species reminds of T. niveum in its choice of habitat on moss-covered rocks. It can, however, be distinguished by its stouter basidiomata and the presence of a brown peristome. Whether or not the flattened stipe is a constant species character cannot be decided from the available material. The spores are similar, as observed from SEM photos (Figure 2j, 6e-g). It is distinguished from T. brumale by the presence of a stout stipe, the less widened capillitial septa, and the larger spores. Also T. simulans is morphologically similar but is recognized by its more slender basidiomata and different habitat and distribution. The two findings of T. eckbladii constitute northern extremities in the distribution of the genus Tulostoma. It has previously been reported and discussed by Brochmann et al. (1981) as Tulostoma sp.

Tulostoma fimbriatum is one of the more frequently recorded species of the genus. It was described by Fries (1829) from southernmost Sweden. In the Elias Fries Herbarium at UPS there is a collection from the type locality (Lomma, S. Sweden; Fries 1829, 1849). On the label there is the handwriting of T. M. Fries (Elias Fries’ son) but the material is likely to be an authentic collection of Elias Fries. The material is scanty (one basidiome glued to a piece of cardboard) with the endoperidial mouth zone destroyed and with indistinct micro-morphological characters. Nevertheless it should be considered a holotype, but since its characteristics are ambiguous, an epitype is here chosen from recently collected and sequenced material originating from southernmost Sweden. Tulostoma fimbriatum can be distinguished from other species with similar macro-morphology by its spores, which have a low ornamentation of verrucae coalescing in ridges and Y-shaped crests (Figure 7c–e). The lectotype of T. campestre (=T. fimbriatum var. campestre) forms a monophyletic clade with T. fimbriatum sensu stricto. As the morphology (Figure 8) also is congruent we regard them as synonymous. See also T. winterhoffii, with which this species has previously been confused.

Habitat and distribution

In dry and exposed habitats; both on calcareous and acidic soils, widespread in Europe reaching 60 'N in Scandinavia. Cosmopolitan distribution but in Europe often confused with the widely distributed T. winterhoffii.

Our sequence data confirm T. fulvellum as a well-defined species in Clade 8, as a sister species to T. lloydii. In agreement with Wright (1987), we consider T. fulvellum to be the valid name for this species.

Habitat and distribution

Tulostoma fulvellum is a species of humus-rich habitats in shaded to semi-shaded habitats. Reported from Europe (France, Germany, Italy, Slovakia, Spain, and Switzerland; Bataille 1910, Candoussau 1973, Jeppson 2008, Kabát 1987, Monthoux and Röllin 1974, Wright 1987) and Japan (Asai and Asai 2008).

ITALY, Trento: in Horto Cappucinarum, 1880, Bresadola (S!)

Our sequence data confirm T. giovanellae as a well-defined species. Morphologically it is characterized by its finely verrucose spores with verrucae arranged in radial lines, as seen under SEM (Figure 2f). Some photos of the holotype collection at S (habit and spore ornamentation under SEM) were included in Altés et al. (1999). Since T. volvulatum is an older synonym, it takes priority over T. giovanellae. Art. 57 of the Melbourne Code allows an exception to the priority rule, preventing the use of a name that incurs in serious conflict with the taxonomic concept traditionally associated with it. Also, Art. 56 allows rejection of a name in that circumstance. A formal proposition will be put forward to the General Committee (to be published in Taxon) that the name T. volvulatum become a nomen rejiciendum, whereas T. giovanellae would be a conserved name to be used in its traditional sense.

A sequence from a collection labelled T. caespitosum var. acaule, originating from Patouillard’s herbarium (BPI), proved to be identical with T. giovanellae. See discussion (below) for issues around interpretation of T. caespitosum and T. caespitosum var. acaule.

Habitat and distribution

Africa, Asia, and Europe. It is a typical Mediterranean species found on sandy or halophytic soils in more or less exposed sites, but it is also recorded from anthropogenic habitats in Austria, Hungary, and Germany (Bohus and Babos 1977, Kreisel 1984, Rimóczi et al. 2011).

The name refers to the large spores.


Spore-sac subglobose, 3–8 mm. Endoperidium hyphal, encrusting sand. Endoperidium greyish white to pale greyish ochraceous with some adhering sand grains, smooth. Mouth fibrillose-fimbriate, slightly mammose (Figure 9f). Socket inconspicuous. Stem slender, 15–23 x 1–2 mm, whitish to pale yellowish brown towards the base, which is slightly widened, covered by sand and provided with a distinct pseudorhiza (Figure 9a,e). Capillitium 3–7 µm in diameter, with irregular, undulating inner walls (Figure 9b). Septa scarce, not or only very slightly widened. Spores subglobose, 5.5–7.0 µm (av. 6.5 µm), smooth under light microscopy and SEM (Figure 9c, g–i).

Habitat and distribution

Recorded in exposed sand steppe habitats in Hungary and Slovakia. Usually not very numerous in its localities.


The species reminds of the new species T. pannonicum in its habit, but a check under the microscope is enough to distinguish T. grandisporum. Tulostoma leiosporum R.E. Fr., described from S. America, is similar to T. grandisporum in macro-morphology but differs in spore size (lectotype: 4.5–5.5 µm according to Moreno et al. 1997). The lectotype of T. leiosporum has the same type of ragged, undulating inner walls of the capillitium.

The studied material fits the original description as well as that of Wright (1987), and it is furthermore supported by ITS sequence data from the holotype. The eight closely related, but still unidentified, species (T. spp. 6-13) recovered in our phylogenetic analysis (Figure 1b) are in need of further investigation before they can be described as distinct and separate species.

Habitat and European distribution

Tulostoma kotlabae occurs in dry and exposed habitats such as steppe vegetation and sand dunes, preferably on calcareous, sandy soils. It is, to date, only known from Europe, from where it is on record from Denmark, France, Germany, Hungary, Lithuania, Poland, Russia (S part), Slovakia, Spain, and Sweden (Calonge 1998, Nitare 1988, Jeppson 2006a, 2008, Rimóczi et al. 2011, Rudnicka-Jezierska 1991, Winterhoff 2000, Wright 1987).

USA (S!).

A characteristic species originally described from N. America. We have not sequenced the holotype, but its macro- and micromorphology (Figure 11a) are very similar to that of the collections here studied (Figure 2h).

Habitat and distribution

Tulostoma lloydii is recorded from N. America and Europe (Wright 1987). In Europe it has a Mediterranean distribution, having been reported from Italy and Spain. According to Wright (1987) it is a species of “forest soil, among humus and plant debris”. The studied material from Italy was collected in a garden, but there are also findings from more xeric environments on calcareous soil and on littoral sand dunes in Spain.

Figure 2i


ITALY: in glabrosis prope Tridentinum, 1902, G. Bresadola (K).

This species is closely related to T. squamosum, T. subsquamosum, and the new species T. calcareum. It is distinguished by its dark brown to almost black stipe and a prominent dark peristome contrasting to the pale colours of the surrounding endoperidium in old and weathered specimens. In young basidiomata the endoperidium is more or less orange brown and the stem ± orange brown. The spores are verrucose-echinate and normally lack anastomoses and crests as seen under SEM (Figure 2i). It can be readily distinguished from T. brumale, which often grows in the same locations, by its darker stem and the more coarsely ornamented spores. Photos of the holotype collection at K (habit and spore ornamentation under SEM) were included in Altés et al. (1996).

Habitat and distribution

Grows in dry sandy grasslands, on sand dunes, sand steppes and rupicolous steppe slopes. According to Wright (1987) it is a typically European species. It is, however, also recorded from Central Asia (Dörfelt and Täglich 1990). It is widespread in Europe, reaching as far north as southernmost Fennoscandia.

Figures 2k, 5c


U.S.A., Colorado, Coke 2715 (K 39158); Isotype: (NY!)*

Sequenced Spanish collections were shown to be identical with the ITS sequence of the isotype from Colorada, USA (Cooke 2715, NY). With respect to morphology, T. obesum reminds of a species reported under T. obesum or T. volvulatum (T. volvulatum var. obesum) by Babos (1999), Calonge (1998), Hollós (1904), and Rimóczi et al. (2011) from the Iberian Peninsula and East Central Europe. However, according to molecular data, those records can be attributed to other species despite sharing a number of morphological features with T. obesum. SEM-photos for T. obesum show completely smooth spores (Figure 2k). Photos of the holotype and isotype collections at K and NY (habit and spore ornamentation under SEM) were included in Altés et al. (1999).

Habitat and distribution

A psammophilous species originally described from Colorado. In Europe it is recorded from littoral sand dunes and halophytic steppe habitats in SE Spain.

The name refers to Pannonia, an ancient Roman province in Central Europe, where this species was first collected.


Spore-sac subglobose, 4–7 mm in diameter. Exoperidium indistinct to thinly membranous, incrusting sand, remaining as a cup-like structure at the base of the spore-sac (Figure 13d). Endoperidium greyish white, smooth, or pitted from detached sand grains. Mouth indistinct to fibrillose-fimbriate (Figure 13f). Socket inconspicuous, slightly separated. Stem slender, 10–20 x 1–2 mm, ochraceous to pale greyish, smooth, somewhat longitudinally furrowed, with a slightly widened base and a distinct pseudorhiza (Figure 13a,d). Mature gleba ferrugineous. Capilltium 3–5 µm in diameter with even inner walls and abundant, strongly widened septa (Figure 13b). The capillitium easily breaks up at the septa. Spores subglobose to broadly ellipsoid, 3.5–4.5 µm (av. 4.0 µm), smooth. Under SEM the spore wall is smooth to slightly rugulose (Figure 13g-i).

Habitat and distribution

The species is recorded from exposed sand steppe habitats on calcareous soil in Hungary.


Rimóczi et al. (2011) recorded this species from Hungary as T. leiosporum and noted that the spores were slightly smaller than those of the lectotype of T. leiosporum, deposited in Herbarium S. Some photos of the lectotype collection of T. leiosporum (habit and spore ornamentation under SEM) were included in Moreno et al. (1997).

Tulostoma pseudopulchellum is a small and slender species with a macro-morphological resemblance to T. pulchellum. It differs from that species by having significantly smaller basidiomata and irregularly rugulose spores (SEM). It has a distinctly membranous exoperidium and a fibrillose-fimbriate mouth. Moreno et al. (1992b) suggested a close relationship with T. pulchellum but this could not be confirmed in the molecular analyses.

This is a characteristic species with a distinct membranous exoperidium, a snow-white endoperidium and a ± delimited, fibrillose-fimbriate mouth. The ornamentation of the spores is composed of a dense cover of low verrucae, sometimes coalescing into ridges. Collections with a ridged type of ornamentation have been distinguished as T. hollosii and T. pulchellum var. subfuscum (cfr. Moreno et al. 1992b, Specht and Schubert 2012). Our sequence data based on specimens with isolated verrucae as well as on those with distinct ridges (Figure 2l), a paratype of T. hollosii included (Figure 15), indicate conspecificity. Our molecular data suggest T. pulchellum to be closely related to T. striatum (Figure 1b).

Habitat and distribution

Tulostoma pulchellum has a cosmopolitan distribution, occurring in exposed, dry, and warm habitats. In Europe it is on record from the Czech Republic, Germany, Hungary, Italy, Romania, Slovakia, and Spain (Kreisel 2001, Kříž 2011, Specht and Schubert 2012, Sarasini 2005). It is here confirmed also from Central Asia (Mongolia).

USA, Kansas: Rooks Co., 23 Jul. 1896, E. Bartholomew (BPI 729033!)*.

The first European records of this traditionally North American species are here confirmed. The species can easily be confused with T. fimbriatum, but is distinguished by the somewhat smaller spores that are more ornamented with a verrucose-spiny ornamentation without ridges (Figure 16a). Study of the macro-micromorphology and sequence data of the type collections of T. punctatum (Figure 17) and T. subfuscum (Figure 18), indicate conspecificity. It is surprising to see that the spore ornamentation of the type of T. subfuscum is very different from the expected one (cfr. description and illustrations by Wright 1987). The presence of distinctive punctate pits on the endoperidium of T. punctatum, as described by Peck (1896), could not be observed in the European specimens. A somewhat pitted appearance of the endoperidium is a common, but inconsistent, feature among species of Tulostoma, and of little taxonomic value. The pits are scars or depressions caused by sand grains adhering to the peridium in early stages of development.

Habitat and distribution

USA, Texas: Denton, Long (herb. Lloyd 13636, BPI 704611).

As was indicated already by its author (Lloyd 1906), this species “simulates” other species of Tulostoma, particularly T. brumale, from which it differs by having a hyphal exoperidium and larger spores. According to our molecular results it is known from Austria, Hungary, Spain, Sweden, and the UK (a British sequence was kindly provided by Martyn Ainsworth, Kew, but is not shown in the tree). Sequence data of the European specimens, labelled as T. beccarianum, T. brumale, and T. moravecii (isotype, Figure 19), cluster with a paratype in PC of T. simulans. Unfortunately the holotype material of T. simulans was not available for DNA extraction.

SEM-photos of the collections used in our study show irregular, rather dense, broadly based conical verrucae (Figure 16b), thus closely coinciding with the holotype material of T. simulans (cfr. Moreno and Altés 1992). Altés and Moreno (1993) synonymized T. simulans with T. beccarianum based on morphological similarities, but sequence data show that they should be regarded as separate species.

Habitat and distribution

N. America, S. America, Australia, New Zealand, Europe, and Asia (Kazachstan). It is here confirmed also from eastern Russia (Altay Republic). It has been found in a wide range of habitats (“forest soil, among litter, sometimes dunicolous, tree nurseries” according to Wright 1987).

European occurrences are from sand steppe habitats, sand dunes, gypsum hills, rupicolous steppe meadows, and urban plantations.

Tulostoma squamosum is morphologically well characterized by its brown, rather tall and squarrose stem combined with a brownish warty exoperidium that upon dehiscense leaves a distinct reticulate pattern. The exoperidium is composed of brownish sphaerocysts. The spore ornamentation under SEM (Figure 16c) shows spines fused at their tops into small pyramidal groups, sometimes coalescing to form short crests. In Scandinavia the name T. squamosum has previously been associated with the proposed new species T. calcareum, described above (cfr. ArtDatabanken 2015, Nitare 1997),

Habitat and distribution

Usually found among herbs in semi-shaded places, including open deciduous forests and gardens. Taking into account its recently established synonyms T. mussooriense and T. verrucosum (Moreno et al. 1992a), it has a cosmopolitan distribution. It seems to be one of the more widespread Tulostoma species in Europe, reaching north to Germany (Kreisel 1984).

As was noted by Cunningham (1925), this species (originally described from Australia) strongly reminds of T. pulchellum (as T. poculatum), but can be readily distinguished by its striate spores (Figure 16d). The molecular results confirm it is a distinct species (Figure 1b).

Habitat and distribution

It is widespread in the Americas, South Africa and Australia (Wright 1987). Altés and Moreno (1991) recorded it from Europe (Spain), where it to date is only known from the city of Madrid. Asai (2004) reported it from Japan and it is now also confirmed to occur in Mongolia. According to Wright (1987) and Calonge (1998) it is a psammophilous species.

Tulostoma subsquamosum is characterized by a hyphal exoperidium with scattered sphaerocyst-like cells. The spores are verrucose-echinate with a tendency to form a subreticulum (Figure 16e). It seems to be one of the more common species in the sand steppe vegetation of Central Hungary, from where it was traditionally recorded as T. squamosum (cfr. Hollós 1904, Rimóczi et al. 2011). In the molecular analyses it comes out as a sister species to T. squamosum (Figure 1c).

Habitat and distribution

Occurs in dry grasslands on sandy-clayish soil. It has a wide distribution in Asia (India, Pakistan), N and S America and Europe (Hungary, Slovakia, Spain).

GERMANY, Rheinland-Pfalz: Hohfels near Grünstadt, 24 May 1987, W. Winterhoff (HAL).

Tulostoma winterhoffii was recently described from Germany. The holotype was not available for sequencing in this study but a paratype, provided by its authors, was sequenced and found to match sequence data of the type material of T. fimbriatum var. heterosporum. In macro-morphology (Figure 5h) T. winterhoffii strongly reminds of T. fimbriatum but important features to distinguish it are the verrucose-echinate spores (no anastomoses seen under SEM; Figure 16f) and the variation in spore size (Wright 1987: up to 9.7 µm in diameter; Specht and Schubert (2013): (4.5–) 5.5–8.5 (–10.3) μm including ornamentation). Our own material shows a similar variation, averaging 5.7 – 6.1 µm, some spores reaching 9 µm. The same can be observed in the type collection of T. fimbriatum var. heterosporum (Figure 20). Based on morphology and sequence data, T. fimbriatum var. heterosporum must thus be considered a distinct species, for which the name T. winterhoffi has priority.

Habitat and distribution

Mostly in dry and sandy habitats in exposed places, on more or less calcareous soils. Currently known from the Czech Republic, Denmark, France, Germany, Hungary, the Netherlands, Norway, Spain, and Sweden. In Scandinavia it reaches 60 ' N. The world distribution comprises Europe, Asia (Caucasus), and N. America (California) according to Wright (1987; as T. fimbriatum var. heterosporum).

In this study, we found that the species diversity of Tulostoma was unexpectedly high, particularly from the arid areas of the world. The majority of the recovered 21 unidentified clades from the phylogenetic analysis (Figure 1a–c) comprise sequence data from specimens collected in dry arid areas of Europe, notably Hungary and Spain. In Europe, the sand steppe vegetation of Hungary has been shown to be exceptionally species rich in gasteroid fungi (Hollós 1904, Rimóczi et al. 2011). The sand steppes of Hungary constitute a western outpost of the Euroasian steppe zone and in this study 14 of the included identified species of Tulostoma occur there, along with nine of the hithero unnamed species. Thus, we confirm the steppe vegetation as a species diversity hot spot for gasteroid fungi. Another identified area with high species diversity is the arid vegetation in the central part of the Iberian Peninsula, where 11 of the identified species and six of the hitherto unnamed species occur.

But species of Tulostoma are not restricted to arid regions only. Studies in the Tropics and temperate woodlands have indicated the presence of new species, growing in shaded, humus-rich, or even humid conditions (Hernández-Caffot et al. 2011). In Europe, there are also a few species that are adapted to grow in shaded and more humid conditions as T. fulvellum, T. lloydii, T. niveum, and T. squamosum.

In contrast to several recent phylogenetic studies of the Basidiomycota, where the traditional generic concepts of morphologically similar groups have shown to be polyphyletic and resulted in a number of new genera and higher taxa (e.g. Lodge et al. 2014, Örstadius et al. 2015, Miettinen et al. 2016, Petersen and Hughes 2016), Tulostoma is here confirmed as monophyletic. However, the recovered tree topology is not in congruence with the current infrageneric classification of Tulostoma (Pouzar 1958, Wright 1987), suggesting that many of the morphological characters used for delimitations are plesiomorphic or homoplasious. The endoperidial mouth region and the exoperidium, the major delimiting characters for the infrageneric classification when based on morphology, are here shown to be incongruent with the phylogeny, as the different types are distributed among the major clades. On the other hand, endo- and exoperidial features, as well as the spore morphology, are here confirmed and shown to be important characters for the delimitation of species.

Wright (1954) and Wright et al. (1972) listed morphological features in Tulostoma and classified their taxonomic importance as “primary” and “secondary”. Wright (1987) divided the genus in two subgenera (Tulostoma and Lacerata), based on features of the mouth. The former subgenus was divided in two series (Brumalia and Fimbriata), each of them containing five sections. In our analyses Clade 3 corresponds more or less with the section Fimbriata, and a supported branch in Clade 9 corresponds partly to section Poculata. However, species belonging to Wright’s sections Brumalia and Hyphales are distributed amongst the major clades and occur in Clades 3, 4, 5, 9, and 10 (Figure 1a–c). A new infrageneric classification of Tulostoma is necessary, but should be done in the light of further taxon sampling, sequence data, and analyses.

Several of the clades include groups with morphologically cryptic speciation, that are distinguished by the molecular data, but for which discriminatory morphological features are ambiguous or lacking. This is particularly evident in Clades 2, 3, 5, and 10, where a number of unidentified taxa from xerothermic habitats were recovered.

The phylogenetic analyses recovered and confirmed the classical, well-known species from Europe, namely T. brumale, T. cyclophorum, T. fimbriatum, T. fulvellum, T. giovanellae, T. kotlabae, T. lloydii, T. melanocyclum, T. pulchellum, and T. squamosum. In addition, one species not previously known from the continent – T. punctatum – was identified. Further Tulostoma calcareum, T. calongei and T. eckbladii are described as new to science. The former has a wide distribution in Europe whereas the two latter are hitherto only known from Central Spain and northernmost Norway respectively.

We also discovered species with misapplied names and two species new to science were identified from the continental sand steppe vegetation in East Central Europe: T. grandisporum and T. pannonicum. These had previously been misinterpreted as T. leiosporum (Jeppson et al. 2011, Rimóczi et al. 2011). The name T. obesum has in current use been applied for a species found in dry sandy habitats in East Central Europe as well as in dry steppic sites on the Iberian Peninsula (Altés et al. 1999, Rimóczi et al. 2011). It is characterized by having smooth spores and a large, whitish spore-sac that opens lacerately at maturity. In this study an ITS sequence from of the isotype of T. obesum (from Colorado, USA) was generated and included in the analyses. It did not form a clade with the European concept of T. obesum but with a hitherto unnamed species in Clade 2, known from sand dune habitats of SE Spain. Thus we here confirm T. obesum from Europe, but with a different species interpretation from that of previous European mycologists (Altés et al. 1999, Rimóczi et al. 2011).

The Hungarian and Spanish collections, previously attributed to T. obesum, are placed in Clade 6 and are here treated as T. aff. cretaceum. This clade consists of a complex of closely related cryptic species with a strong geographical signal. In East Central Europe and Central Asia the name T. volvulatum I.G. Borshch. has been misapplied to cover this species complex (e.g. Hollós 1904, Shvartsman and Filimonova 1970). As demonstrated by Altés et al. (1999), the holotype of T. volvulatum was based on a specimen of T. giovanellae, with typical ornamented spores. Under the name T. volvulatum, Hollós (1904) recorded T. giovanellae (e.g. S, F265540) but also specimens with smooth spores (Babos 1999) that closely match Sorokin´s (1890) interpretation of T. volvulatum from the Karakoum Desert (Sorokin 1890, plate XXV, Figure 353a). A number of poorly known species described from desert habitats in northern Africa (e.g. T. barbeyanum Henn., T. boissieri Kalchbr., T. giolianum Bacc., and T. ruhmerianum Henn.) as well as the American T. cretaceum Long and T. meristostoma Long, share characters typical of this clade and need to be included in an extended study, which should also deal with several recently described species from China (T. brevistipitatum B. Liu, Z.Y. Li & Du, T. sabulosum B. Liu, Z.Y. Li & Du, and T. helanshanense B. Liu, Z.Y. Li & Du). Calonge (1998) identified Spanish material attributed to T. volvulatum as Schizostoma laceratum (Ehrenb.: Fr.) Lév. Based on sequence data, Gube (2009) recovered S. laceratum as closely related to the type of T. cretaceum. As pointed out by Kuhar et al. (2012), the whole complex is in need of a detailed study comprising morphological as well as molecular data. Similarly, the status of the genus Schizostoma is unclear and calls for further study.

Tulostoma simulans is here identified from Europe. According to our data it seems to have a wide distribution but appears to be rare. The species is known from East Central Europe under the name T. moravecii, and it may have been overlooked due to its resemblance with T. brumale.

The application of the name Tulostoma caespitosum Trab. is an unsolved problem. The species was described from northern Africa and later reported from the Americas, Asia, and Europe (Calonge 1998, Calonge and Wright 1988, Wright 1987). Among its main characteristics, according to Wright (1987), are the distorted basidiomata and the sometimes caespitose growth. Wright (1987) did not find any collection that he considered to be suitable as a holotype and suggested a neotype, collected by Trabut in Algeria, coinciding with the protologue of T. caespitosum (T. caespitosum var. acaule, herb. Patouillard 1422, FH; unpublished herbarium name). However, Wright did not formally designate a neotype. An authentic collection of T. caespitosum var. acaule, from Algeria (leg. Trabut), is kept in BPI (ex herb. Patouillard, herb. Lloyd 15427, BPI 704324) but was unfortunately found to be in poor condition and too scanty for DNA sequencing. A second collection from Africa (indet. region) in BPI (Patouillard 4639, herb. Lloyd 15426, BPI 704323) was sequenced for the present study and found to be identical with T. giovanellae, in Clade 10, Figure 1c. The spore ornamentation of this specimen is identical to T. giovanellae. However, in collection BPI 704324 the spores were shown to be strongly verrucose, thus differing from T. giovanellae. The typification of T. caespitosum thus remains unsettled and the unclear interpretation of this name calls for further study.

Kreisel and Al-Fatimi (2008) observed that gasteroid basidiomycetes from desert habitats tend to produce smooth spores. This stands in contrast to taxa growing in vegetation types that are regularly exposed to rainfall – these usually have more or less distinctly ornamented, verrucose–echinate spores. Kuhar et al. (2012) found that the relative abundance of species with smooth spores within the study in Argentina reached a maximum under desert conditions. The relative abundance of species with ornamented spores was shown to go up with increasing humidity. Their hypothetical explanation was that the spore wall ornamentation increases the water repellency, favouring a wind-blown dispersal (Kreisel and Al-Fatimi 2008).

In this study, species of Tulostoma with smooth or sub-smooth spores are found to occur mainly in arid, and exposed habitats in East Central Europe and Spain (T. aff. cretaceum, T. grandisporum, T. obesum, T. pannonicum). Species with moderately to strongly ornamented spores (T. beccarianum, T. brumale, T. calongei, T. giovanellae, T. melanocyclum, T. punctatum, T. simulans, and T. subsquamosum) are found in more steppic, dry grassland communities in southern and east central Europe. In semi-shaded or shaded to somewhat humid habitats, the genus is represented by species with ornamented spores (T. cyclophorum, T. niveum, and T. squamosum) but also a few with completely smooth spores (T. fulvellum and T. lloydii). Among the species regularly encountered in northern and north-western Europe, i.e. in sub-oceanic or oceanic climates, all have moderately to distinctly ornamented spores (T. eckbladii, T. brumale, T. calcareum, T. fimbriatum, T. kotlabae, T. melanocyclum, T. niveum, T. simulans, T. squamosum, and T. winterhoffii). In accord with the observations by Kreisel and Al-Fatimi (2008), Tulostoma species with smooth or sub-smooth spores tend to occur mainly in dry and arid habitats whereas those with distinct and strongly ornamented spores grow in more humid habitats.

Due to difficulties to determine Tulostoma specimens to species level, many published records and herbarium collections are based on misinterpretations. It is therefore problematic to evaluate species distribution data. Some seem to have wide, more or less cosmopolitan distribution ranges (e.g. T. fimbriatum, T. pulchellum, T. striatum, T. squamosum, and T. subsquamosum). Others appear to be restricted to certain geographical areas or habitat types (e.g. T. grandisporum, T. pannonicum, T. niveum, and T. eckbladii). In Europe most species have southern and southeastern distributions. The number of species decreases towards the north. Tulostoma brumale, T. calcareum, T. fimbriatum, T. kotlabae, T. melanocyclum, T. simulans, and T. winterhoffii reach the south of Fennoscandia, whereas T. niveum is regularly found between 55° and 62° N, from southern Finland westwards to northern Scotland. The report herein of T. niveum from near Geneva in Switzerland is a significant range extension. The newly described species, T. eckbladii, is, as far as currently known, limited to areas above the Arctic Circle.

A number of species of Tulostoma occur in habitat types that are under the threat of changing agricultural methods, anthropogenic exploitation, and construction works. Hernández-Caffot et al. (2011) described T. domingueziae from threatened woodland ecosystems in Argentina. In Europe, several Tulostoma species are on the red-list of threatened species in the countries where they occur: T. brumale, T. fimbriatum, T. kotlabae, T. melanocyclum, T. simulans (as T. moravecii), T. pulchellum, and T. niveum (ArtDatabanken 2015, ArtsDatabanken 2015, Holec and Beran 2006, Rassi et al. 2010). For T. niveum, national action plans for its conservation have been elaborated and become effective in Great Britain and Sweden (BAP 2005, Jeppson 2005, 2006b). Tulostoma niveum has also been nominated for the IUCN global red-list ( and T. aff. cretaceum (as T. volvulatum) is legally protected in Hungary (Siller et al. 2005). Many species of Tulostoma can be considered as indicators of valuable and threatened habitats.

In this study we show, based on molecular data, that the species diversity of Tulostoma is much higher than previously known. Much of this detected diversity is associated with dry, arid areas, such as the steppe vegetation in Hungary. This suggests that the number of species is likely to increase even more as other dry areas of the world are explored.
