Abstract: In this study, two new species, Rhizoplaca adpressa Y. Y. Zhang & Li S. Wang and R. auriculata Y. Y. Zhang, Li S. Wang & Printzen, are described from Southwest China, based on their morphology, phylogeny and chemistry. In phylogeny, the two new species are monophyletic, and sister to each other within Rhizoplaca chrysoleuca-complex. Rhizoplaca adpressa is characterized by its placodioid and closely adnate thallus, pale green and heavily pruinose upper surface, narrow (ca. 1 mm) and white free margin on the lower surface of marginal squamules, the absence of a lower cortex, and its basally non-constricted apothecia with orange discs that turn reddish-brown at maturity. Rhizoplaca auriculata is characterized by its squamulose to placodioid thallus, yellowish green and marginally pruinose squamules, wide (1−3 mm) and bluish-black free margin on the lower surface of marginal squamules, the absence of a lower cortex, and its basally constricted apothecia with persistently orange discs. Rhizoplaca adpressa and R. auriculata share the same secondary metabolites of usnic and placodiolic acids.

Roccellinastrum, Cenozosia and Heterodermia: Ecology and phylogeny of fog lichens and their photobionts from the coastal Atacama Desert https://mycokeys.pensoft.net/article/107764/ MycoKeys 98: 317-348

DOI: 10.3897/mycokeys.98.107764

Authors: Patrick Jung, Lina Werner, Laura Briegel-Williams, Dina Emrich, Michael Lakatos

Abstract: Some deserts on Earth such as the Namib or the Atacama are influenced by fog which can lead to the formation of local fog oases - unique environments hosting a great diversity of specialized plants and lichens. Lichens of the genera Ramalina, Niebla or Heterodermia have taxonomically been investigated from fog oases around the globe but not from the Atacama Desert, one of the oldest and driest deserts. Conditioned by its topography and the presence of orographic fog, the National Park Pan de Azúcar in the Atacama Desert is considered to be such a lichen hotspot. Applying multi-gen loci involving phylogenetic analyses combined with intense morphological and chemical characterization, we determined the taxonomic position of five of the most abundant epiphytic lichens of this area. We evaluated Roccellinastrum spongoideum and Heterodermia follmannii which were both described from the area but also finally showed that the genus Cenozosia is the endemic sister genus to Ramalina, Vermilacinia, Namibialina and Niebla. As a result, we have described the species Heterodermia adunca, C. cava and C. excorticata as new lichen species. This work provides a comprehensive dataset for common fog lichen genera of the Coastal Range of the Atacama Desert that can be used as a baseline for monitoring programs and environmental health assessments.

Pseudolepraria, a new leprose genus revealed in Ramalinaceae (Ascomycota, Lecanoromycetes, Lecanorales) to accommodate Lepraria stephaniana https://mycokeys.pensoft.net/article/98029/ MycoKeys 96: 97-112

DOI: 10.3897/mycokeys.96.98029

Authors: Martin Kukwa, Magdalena Kosecka, Agnieszka Jabłońska, Adam Flakus, Pamela Rodriguez-Flakus, Beata Guzow-Krzemińska

Abstract: The new genus Pseudolepraria Kukwa, Jabłońska, Kosecka & Guzow-Krzemińska is introduced to accommodate Lepraria stephaniana Elix, Flakus & Kukwa. Phylogenetic analyses of nucITS, nucLSU, mtSSU and RPB2 markers recovered the new genus in the family Ramalinaceae with strong support. The genus is characterised by its thick, unstratified thallus composed entirely of soredia-like granules, the presence of 4-O-methylleprolomin, salazinic acid, zeorin and unknown terpenoid, and its phylogenetic position. The new combination, P. stephaniana (Elix, Flakus & Kukwa) Kukwa, Jabłońska, Kosecka & Guzow-Krzemińska, is proposed.

Mycobiont-specific primers facilitate the amplification of mitochondrial small subunit ribosomal DNA: a focus on the lichenized fungal genus Melanelia (Ascomycota, Parmeliaceae) in Iceland https://mycokeys.pensoft.net/article/100037/ MycoKeys 96: 57-75

DOI: 10.3897/mycokeys.96.100037

Authors: Maonian Xu, Yingkui Liu, Erik Möller, Scott LaGreca, Patricia Moya, Xinyu Wang, Einar Timdal, Hugo de Boer, Eva Barreno, Lisong Wang, Holger Thüs, Ólafur Andrésson, Kristinn Pétur Magnússon, Elín Soffia Ólafsdóttir, Starri Heiðmarsson

Abstract: The fungal mitochondrial small subunit (mtSSU) ribosomal DNA is one of the most commonly used loci for phylogenetic analysis of lichen-forming fungi, but their primer specificity to mycobionts has not been evaluated. The current study aimed to design mycobiont-specific mtSSU primers and highlights their utility with an example from the saxicolous lichen-forming fungal genus Melanelia Essl. in Iceland. The study found a 12.5% success rate (3 out of 24 specimens with good-quality mycobiont mtSSU sequences) using universal primers (i.e. mrSSU1 and mrSSU3R), not including off-target amplification of environmental fungi, e.g. Cladophialophora carrionii and Lichenothelia convexa. New mycobiont-specific primers (mt-SSU-581-5’ and mt-SSU-1345-3’) were designed by targeting mycobiont-specific nucleotide sites in comparison with environmental fungal sequences, and assessed for mycobiont primer specificity using in silico PCR. The new mycobiont-specific mtSSU primers had a success rate of 91.7% (22 out of 24 specimens with good-quality mycobiont mtSSU sequences) on the studied Melanelia specimens. Additional testing confirmed the specificity and yielded amplicons from 79 specimens of other Parmeliaceae mycobiont lineages. This study highlights the effectiveness of designing mycobiont-specific primers for studies on lichen identification, barcoding and phylogenetics.

A new species of Megalaria (Ramalinaceae, Ascomycota) from Thailand, and recognition of subgenus Catillochroma https://mycokeys.pensoft.net/article/90962/ MycoKeys 93: 149-163

DOI: 10.3897/mycokeys.93.90962

Authors: Phimpisa Phraphuchamnong, Matthew P. Nelsen, Isabel Distefano, Joel A. Mercado-Diaz, Sittiporn Parnmen, Achariya Rangsiruji, Kawinnat Buaruang, Robert Lücking, H. Thorsten Lumbsch

Abstract: Tropical regions harbor a substantial diversity of lichenized fungi, but face numerous threats to their persistence, often even before previously unknown species have been described and their evolutionary relationships have been elucidated. Megalaria (Ramalinaceae) is a lichen-forming genus of fungi that produces crustose thalli, and includes a number of lineages occupying tropical rain forests; however, taxonomic and phylogenetic work on this clade is limited. Here we leverage both morphological and sequence data to describe a new species from the tropics, M. pachaylenophila. This taxon forms a crustose thallus, lacks secondary metabolites, and occurs in mangrove forests of Thailand. We supplemented molecular data from this species with data from other species, including two genera related to and occasionally included in Megalaria, namely Catillochroma and Lopezaria. Our analyses revealed Catillochroma species form a monophyletic group embedded within Megalaria, and we therefore recognize this clade at the subgeneric level. Since we only included the type species of Lopezaria in this study, we refrain from proposing a taxonomic conclusion for that clade at the moment. Several taxonomic combinations are made to reflect phylogenetic evidence supporting the inclusion of these species in Megalaria.

Infraspecific variation of some brown Parmeliae (in Poland) – a comparison of ITS rDNA and non-molecular characters https://mycokeys.pensoft.net/article/70552/ MycoKeys 85: 127-160

DOI: 10.3897/mycokeys.85.70552

Authors: Katarzyna Szczepańska, Beata Guzow-Krzemińska, Jacek Urbaniak

Abstract: Infraspecific variation of the ITS rDNA region of some brown Parmeliae occurring in Poland is studied and compared with non-molecular characters. Haplotype networks are used to illustrate the variability within the species. Both newly-produced sequences from Central Europe and from all over the world, downloaded from the GenBank, are used. The number of haplotypes found for each taxon ranged from five in Melanelia stygia to 12 in Melanelia hepatizon and Montanelia disjuncta; however, their numbers correlate with the number of specimens tested. New haplotypes for Melanelia agnata, M. hepatizon and Cetraria commixta are found. Based on our 169-sample dataset, we could not infer any geographical correlation, either locally or world-wide. Many of the analysed haplotypes were widely distributed and the same haplotype was often shared between temperate and polar populations. A comparison of molecular, morphological, anatomical and chemical characters also shows no correlation.

Two new lecanoroid lichen species from the forested wetlands of South Korea, with a key for Korean Protoparmeliopsis species https://mycokeys.pensoft.net/article/70798/ MycoKeys 84: 163-183

DOI: 10.3897/mycokeys.84.70798

Authors: Beeyoung Gun Lee, Jae-Seoun Hur

Abstract: Lecanora parasymmicta Lee & Hur and Protoparmeliopsis crystalliniformis Lee & Hur are described as new lichen species to science from the forested wetlands in southern South Korea. Molecular analyses employing internal transcribed spacer (ITS) and mitochondrial small subunit (mtSSU) sequences strongly support the two lecanoroid species to be distinct in their genera. Lecanora parasymmicta is included in the Lecanora symmicta group. It is morphologically distinguished from Lecanora symmicta (Ach.) Ach., its most similar species, by areolate-rimose thallus, blackish hypothallus, larger apothecia, absence of thalline excipulum from the beginning, narrower paraphyses, larger ascospores, smaller pycnoconidia, and the presence of placodiolic acid. The second new species Protoparmeliopsis crystalliniformis is included in a clade with Protoparmeliopsis bipruinosa (Fink) S.Y. Kondr. and P. nashii (B.D. Ryan) S.Y. Kondr., differs from Protoparmeliopsis ertzii Bungartz & Elix, its most morphologically similar species, by whitish thallus, flat to concave and paler disc, longer ascospores, thallus K+ yellow reaction, presence of atranorin and rhizocarpic acid, and the substrate preference to sandstone or basalt. A key is provided to assist in the identification of Protoparmeliopsis species in Korea.

Morphology and secondary chemistry in species recognition of Parmelia omphalodes group – evidence from molecular data with notes on the ecological niche modelling and genetic variability of photobionts https://mycokeys.pensoft.net/article/38175/ MycoKeys 61: 39-74

DOI: 10.3897/mycokeys.61.38175

Authors: Emilia Ossowska, Beata Guzow-Krzemińska, Marta Kolanowska, Katarzyna Szczepańska, Martin Kukwa

Abstract: To evaluate the importance of morphological and chemical characters used in the recognition of species within the Parmelia omphalodes group, we performed phylogenetic, morphological and chemical analyses of 335 specimens, of which 34 were used for molecular analyses. Phylogenetic analyses, based on ITS rDNA sequences, show that P. pinnatifida is distinct from P. omphalodes and the most important difference between those species is the development of pseudocyphellae. In P. pinnatifida, they are mostly marginal and form white rims along lobes margins, but laminal pseudocyphellae can develop in older parts of thalli and are predominantly connected with marginal pseudocyphellae. In contrast, in P. omphalodes laminal pseudocyphellae are common and are predominantly not connected to marginal pseudocyphellae. Chemical composition of secondary lichen metabolites in both analysed species is identical and therefore this feature is not diagnostic in species recognition. Few samples of P. discordans, species morphologically similar to P. omphalodes and P. pinnatifida, were also included in the analyses and they are nested within the clade of P. omphalodes, despite the different chemistry (protocetraric acid present versus salazinic acid in P. omphalodes). All taxa of the P. omphalodes group occupy similar niches, but their potential distributions are wider than those currently known. The absence of specimens in some localities may be limited by the photobiont availability. Parmelia omphalodes and P. pinnatifida are moderately selective in photobiont choice as they form associations with at least two or three lineages of Trebouxia clade S. Parmelia pinnatifida, as well as P. discordans are associated with Trebouxia OTU S02 which seems to have a broad ecological amplitude. Other lineages of Trebouxia seem to be rarer, especially Trebouxia sp. OTU S04, which is sometimes present in P. pinnatifida. This study indicates the importance of extensive research including morphology, chemistry and analysis of molecular markers of both bionts in taxonomical studies of lichens.

Microsatellite based genetic diversity of the widespread epiphytic lichen Usnea subfloridana (Parmeliaceae, Ascomycota) in Estonia: comparison of populations from the mainland and an island https://mycokeys.pensoft.net/article/36557/ MycoKeys 58: 27-45

DOI: 10.3897/mycokeys.58.36557

Authors: Polina Degtjarenko, Inga Jüriado, Tiina Mandel, Tiiu Tõrra, Andres Saag, Christoph Scheidegger, Tiina Randlane

Abstract: Understanding the distribution of genetic patterns and structure is an essential target in population genetics and, thereby, important for conservation genetics. The main aim of our study was to investigate the population genetics of Usnea subfloridana, a widespread lichenised fungus, focusing on a comparison of genetic variation of its populations amongst three geographically remote and disconnected regions, in order to determine relationships amongst environmental data, variation in lichen secondary chemistry and microsatellite data in genotyped populations. In all, 928 Usnea thalli from 17 populations were genotyped using seven specific fungal microsatellite markers. Different measures of genetic diversity (allelic richness, private allelic richness, Nei’s unbiased genetic diversity and clonal diversity) were calculated and compared between lichen populations. Our results revealed a low genetic differentiation of U. subfloridana populations amongst three distant areas in Estonia and also a high level of gene flow. The results support suggestion of the long-range vegetative dispersal of subpendulous U. subfloridana via symbiotic propagules (soralia, isidia or fragments of thalli). Our study has also provided evidence that environmental variables, including mean annual temperature and geographical longitude, shape the genetic structure of U. subfloridana populations in Estonia. Additionally, a weak but statistically significant correlation between lichen chemotypes and microsatellite allele distribution was found in genotyped specimens.

A regional study of the genus Phyllopsora (Ramalinaceae) in Asia and Melanesia https://mycokeys.pensoft.net/article/33425/ MycoKeys 53: 23-72

DOI: 10.3897/mycokeys.53.33425

Authors: Sonja Kistenich, Mika Bendiksby, Charles S. Vairappan, Gothamie Weerakoon, Siril Wijesundara, Patricia A. Wolseley, Einar Timdal

Abstract: Phyllopsora is a crustose to squamulose lichen genus inhabiting the bark of trees in moist tropical forests and rainforests. Species identification is generally challenging and is mainly based on ascospore morphology, thallus morphology and anatomy, vegetative dispersal units, and on secondary chemistry. While regional treatments of the genus have been conducted for Africa, South America and Australia, there exists no study focusing on the Asian and Melanesian species. Previously, 24 species of Phyllopsora s. str. have been reported from major national studies and checklists representing 13 countries. We have studied herbarium material of 625 Phyllopsora specimens from 18 countries using morphology, anatomy, secondary chemistry, and molecular data to investigate the diversity of Phyllopsora species in Asia and Melanesia. We report the occurrence of 28 species of Phyllopsora including the following three species described as new to science: P. sabahana from Malaysia, P. siamensis from Thailand and P. pseudocorallina from Asia and Africa. Eight species are reported as new to Asia. A key to the Asian and Melanesian species of Phyllopsora is provided.

Biatora alnetorum (Ramalinaceae, Lecanorales), a new lichen species from western North America https://mycokeys.pensoft.net/article/33001/ MycoKeys 48: 55-65

DOI: 10.3897/mycokeys.48.33001

Authors: Stefan Ekman, Tor Tønsberg

Abstract: Biatora alnetorum S. Ekman & Tønsberg, a lichenised ascomycete in the family Ramalinaceae (Lecanorales, Lecanoromycetes), is described as new to science. It is distinct from other species of Biatora in the combination of mainly three-septate ascospores, a crustose thallus forming distinctly delimited soralia that develop by disintegration of convex pustules and the production of atranorin in the thallus and apothecia. The species is known from the Pacific Northwest of North America, where it inhabits the smooth bark of Alnus alnobetula subsp. sinuata and A. rubra. Biatora alnetorum is also a new host for the lichenicolous ascomycete Sclerococcum toensbergii Diederich.

Bacidia albogranulosa (Ramalinaceae, lichenized Ascomycota), a new sorediate lichen from European old-growth forests https://mycokeys.pensoft.net/article/30199/ MycoKeys 44: 51-62

DOI: 10.3897/mycokeys.44.30199

Authors: Jiří Malíček, Zdeněk Palice, Jan Vondrák, Anna Łubek, Martin Kukwa

Abstract: A sterile sorediate member of the genus Bacidia s.str., B. albogranulosa, is described here as a new species. It is characterised by its very thin, pale grey thallus, white, farinose to granular soredia, the production of atranorin and the absence of ascomata and pycnidia. It grows on slightly acidic to subneutral bark of broad-leaved trees in old-growth forests in the Czech Republic, Poland, Ukraine and Russia (European part of the Caucasus). The new species is well characterised by its morphology, secondary chemistry and molecular (nrITS, mtSSU) traits. It is closely related to other atranorin-containing species in the genus, Bacidia diffracta, B. polychroa and B. suffusa.

Population genomic analyses of RAD sequences resolves the phylogenetic relationship of the lichen-forming fungal species Usnea antarctica and Usnea aurantiacoatra https://mycokeys.pensoft.net/article/29093/ MycoKeys 43: 91-113

DOI: 10.3897/mycokeys.43.29093

Authors: Felix Grewe, Elisa Lagostina, Huini Wu, Christian Printzen, H. Thorsten Lumbsch

Abstract: Neuropogonoid species in the lichen-forming fungal genus Usnea exhibit great morphological variation that can be misleading for delimitation of species. We specifically focused on the species delimitation of two closely-related, predominantly Antarctic species differing in the reproductive mode and representing a so-called species pair: the asexual U. antarctica and the sexual U. aurantiacoatra. Previous studies have revealed contradicting results. While multi-locus studies based on DNA sequence data provided evidence that these two taxa might be conspecific, microsatellite data suggested they represent distinct lineages. By using RADseq, we generated thousands of homologous markers to build a robust phylogeny of the two species. Furthermore, we successfully implemented these data in fine-scale population genomic analyses such as DAPC and fineRADstructure. Both Usnea species are readily delimited in phylogenetic inferences and, therefore, the hypothesis that both species are conspecific was rejected. Population genomic analyses also strongly confirmed separated genomes and, additionally, showed different levels of co-ancestry and substructure within each species. Lower co-ancestry in the asexual U. antarctica than in the sexual U. aurantiacoatra may be derived from a wider distributional range of the former species. Our results demonstrate the utility of this RADseq method in tracing population dynamics of lichens in future analyses.

Characterization of microsatellite markers in the cosmopolitan lichen-forming fungus Rhizoplaca melanophthalma (Lecanoraceae) https://mycokeys.pensoft.net/article/9729/ MycoKeys 14: 31-36

DOI: 10.3897/mycokeys.14.9729

Authors: Hanna Lindgren, Steven D. Leavitt, Thorsten Lumbsch

Abstract: Rhizoplaca melanophthalma s.l. is a group of morphologically distinct and chemically diverse species that commonly occur in desert, steppe and montane habitats worldwide. In this study, we developed microsatellite markers to facilitate studies of genetic diversity, population structure, and gene flow in the nominal taxon of this group, Rhizoplaca melanophthalma. We characterized 10 microsatellite markers using a draft genome of R. melanophthalma s. str. assembled from Illumina reads. These loci were tested for 21 R. melanophthalma s. str. specimens and also with a subset of 18 specimens representing six additional species in the R. melanophthalma complex. The number of alleles per locus in R. melanophthalma s. str. ranged from 3 to 11 with an average of 6.7. Nei’s unbiased gene diversity ranged from 0.35 to 0.91. Amplifications of the microsatellite loci were largely successful in the other six species, although only three markers were found to be polymorphic. The new markers will provide an additional resource for studying genetic, population- and landscape-level processes in the cosmopolitan taxon Rhizoplaca melanophthalma s. str.

Psora altotibetica (Psoraceae, Lecanorales), a new lichen species from the Tibetan part of the Himalayas https://mycokeys.pensoft.net/article/8824/ MycoKeys 13: 35-48

DOI: 10.3897/mycokeys.13.8824

Authors: Einar Timdal, Walter Obermayer, Mika Bendiksby

Abstract: In the present study, we describe the new species, Psora altotibetica, from nine localities in China (Tibetan area) and Nepal. The study includes analyses of anatomy, secondary chemistry, and DNA sequence data of P. altotibetica and presumed close relatives. Psora altotibetica resembles P. indigirkae morphologically, but is phylogenetically closer to P. tenuifolia and P. vallesiaca. It differs from P. indigirkae in the colour of the apothecia, the size of the ascospores, and in the secondary chemistry. The species is terricolous and was collected in the alpine zone of the Great Himalayas between 4230 and 5000 m altitude. Psora tenuifolia and P. vallesiaca are here reported as new to China and the Himalayas.
