Morphological and Multi-Gene Phylogenetic Analyses Reveal Pseudotubeufia gen. nov. and Two New Species in Tubeufiaceae from China.

ABSTRACT: Three helicosporous hyphomycete collections representing two species were obtained from rotting wood found in freshwater and terrestrial habitats in the Guizhou and Guangxi Provinces, China. A new genus Pseudotubeufia (Tubeufiaceae, Tubeufiales), comprising Ps. hyalospora sp. nov. and Ps. laxispora sp. nov., was introduced with morphological characteristic and molecular data. In addition, the molecular evidence showed that Helicomyces sp. (G.M. 2020-09-19.1), H. roseus (CBS: 102.76), and the new genus Pseudotubeufia clustered together with high support based on a multi-gene (LSU, ITS, tef1α, and rpb2) phylogenetic analysis. Detailed descriptions, illustrations, and notes of the three new collections are provided.

Crassisporus gen. nov. (Polyporaceae, Basidiomycota) evidenced by morphological characters and phylogenetic analyses with descriptions of four new species.

Project description:A new poroid wood-inhabiting fungal genus, Crassisporus gen. nov., is proposed on the basis of morphological characters and molecular evidence. The genus is characterized by an annual growth habit, effused-reflexed to pileate basidiocarps with pale yellowish brown to yellowish brown, concentrically zonate or sulcate, and velutinate pileal surface, a trimitic hyphal system with clamped generative hyphae, tissues turning to dark in KOH, oblong to broadly ellipsoid, hyaline, smooth, and slightly thick-walled basidiospores. Phylogenetic analysis based on ITS+nLSU sequences indicate that Crassisporus belongs to the core polyporoid clade. The combined ITS+nLSU+mtSSU+EF1-α+RPB2 sequences dataset of representative taxa in the Polyporaceae demonstrate that Crassisporus is grouped with Haploporus but forms a monophyletic lineage. In addition, four new species of Crassisporus, C. imbricatus, C. leucoporus, C. macroporus, and C. microsporus are described.

Multi-locus phylogenetic analyses reveal eight novel species of Distoseptispora from southern China.

Project description:Plant debris are habitat favoring the growth of various microbial species. Over the course of our mycological surveys in Jiangxi and Yunnan Provinces, China, eight new Distoseptispora species, viz. D. gasaensis, D. guanshanensis, D. jinghongensis, D. longnanensis, D. menghaiensis, D. menglunensis, D. nanchangensis, and D. yichunensis collected on dead branches of unidentified plants, were introduced by morphological and molecular phylogenetic analyses. Multi-locus (LSU, ITS, TEF1, and RPB2) phylogenetic analyses were performed using maximum-likelihood and Bayesian inference to infer their taxonomic positions within Distoseptispora. Both molecular phylogenetic analyses and morphological characters supported them as eight independent taxa within Distoseptispora. This work improves our understanding of the diversity of Distoseptispora in southern China.IMPORTANCEDistoseptispora as a single genus in Distoseptisporaceae was introduced by morphological and phylogenetic analyses. Members of this genus occur mainly as asexual morphs, forming effuse, hairy colonies on decaying wood, plant stems, bamboo culms, and fallen leaves and shafts in terrestrial and freshwater habitats. In the present study, saprobic hyphomycetes from plant debris were investigated, and eight new Distoseptispora species were introduced based on morphology and phylogenetic analyses of LSU, ITS, TEF1, and RPB2 sequence data. This study provides important data on the species diversity, ecological environment, and geographical area of Distoseptispora, greatly updates the classification of Distoseptispora, and improves our understanding of the taxonomy of Distoseptispora.
