Abstract: Phylogenetically, the genera Cuphophyllus, Ampulloclitocybe and Cantharocybe are treated as basal in the family Hygrophoraceae, despite weak support. However, the exact phylogenetic positions of the three genera have remained unresolved, and taxa related to these genera are poorly known. In this study, a new clitocyboid genus Spodocybe was proposed based on multigenic phylogenetic inference datasets and morphological evidence. The analyses of ITS as well as two combined datasets ITS-nrLSU-rpb2 and ITS-nrLSU-rpb1-rpb2-tef1-α-atp6 supported that (1) Spodocybe formed a well-supported monophyletic clade; and (2) sisters Spodocybe and Ampulloclitocybe, along with Cantharocybe and Cuphophyllus also formed a monophyletic lineage, as sister to the rest of the Hygrophoraceae. Meanwhile, two new species, namely S. rugosiceps and S. bispora, from southwestern China, were documented and illustrated. These results support the new proposed genus Spodocybe, and that Spodocybe, Ampulloclitocybe, Cantharocybe and Cuphophyllus should be retained in the Hygrophoraceae as a new subfamily Cuphophylloideae.

Three new species from Guangdong Province of China, and a molecular assessment of Hygrocybe subsection Hygrocybe https://mycokeys.pensoft.net/article/59600/ MycoKeys 75: 145-161

DOI: 10.3897/mycokeys.75.59600

Authors: Chao-Qun Wang, Ming Zhang, Tai-Hui Li

Abstract: Blackening waxcaps (Hygrocybe subsect. Hygrocybe) are a group of colorful and attractive mushrooms. However, the species diversity of subsect. Hygrocybe in China is still poorly known due to the limited sampling. In this study, three new species of this group from Guangdong Province, China are described and illustrated based on their morphological characteristics and molecular analyses of the internal transcribed spacer and large subunit ribosomal DNA regions. Hygrocybe debilipes from grasslands of South China Sea islands is mainly characterized by its orange red to vivid red pileus, fragile stipe, and ellipsoid to oblong basidiospores; H. griseonigricans from woodlands is characterized by its whitish to dull yellow pileus, quick black discoloration and the globose, subglobose to broadly ovoid basidiospores; H. rubroconica from woodlands is characterized by the hemispheric to plano-convex pileus when mature, semitranslucent fibrose stipe, and globose to ellipsoid basidiospores.

Hygrophorus subsection Hygrophorus (Hygrophoraceae, Agaricales) in China https://mycokeys.pensoft.net/article/53264/ MycoKeys 68: 49-73

DOI: 10.3897/mycokeys.68.53264

Authors: Chao-Qun Wang, Tai-Hui Li, Ming Zhang, Xiao-Lan He, Wei-Qiang Qin, Tie-Zhi Liu, Nian-Kai Zeng, Xiang-Hua Wang, Jian-Wei Liu, Tie-Zheng Wei, Jiang Xu, Yue-Qiu Li, Ya-Heng Shen

Abstract: Hygrophorus subsect. Hygrophorus has been relatively well-studied in Europe and North America, but studies on the taxa in Asia, particularly in China, are still limited. In this study, phylogenetic overviews of genus Hygrophorus, based on the nuclear large subunit (LSU) ribosomal RNA gene and of subsect. Hygrophorus, based on the nuclear ribosomal internal transcribed spacer (ITS) regions were generated. Four new species, i.e. H. brunneodiscus, H. fuscopapillatus, H. glutiniceps and H. griseodiscus are described from southern China; and a rarely reported edible species H. hedrychii is described in detail, based upon the materials from north-eastern China. The main characteristics of the species under subsect. Hygrophorus worldwide are summarised in a table.

Gliophorus glutinosus sp. nov. (Hygrophoraceae, Agaricales) from Eastern Himalayan region of India https://mycokeys.pensoft.net/article/28554/ MycoKeys 44: 123-135

DOI: 10.3897/mycokeys.44.28554

Authors: Dyutiparna Chakraborty, Kanad Das, Alfredo Vizzini

Abstract: An interesting species of the genus Gliophorus (sect. Glutinosae), collected from Sikkim Himalaya in India, is described here as G. glutinosus sp. nov. after thorough morphological examination and phylogenetic analysis. The species is mainly characterised by its strongly glutinous basidiomata throughout, particularly on the twisted stipe, decurrent lamellae with glutinous edge, gelatinised cheilocystidia, presence of pleuropseudocystidia and absence of clamps in hyphae of the pileipellis. This communication includes detailed morphological description, illustrations, comparison with the allied taxa, nrITS based phylogeny of this novel taxon and a key to the species under Gliophorus sect. Glutinosae.
