This study collected and isolated saprobic hyphomycetes associated with dead bamboo in Yunnan Province, China and introduced a novel species, Hyalinostachys dehongensis in the family Stachybotryaceae of Ascomycota, introduced here as a novel species.
Abstract
China has abundant bamboo resources, among which Yunnan Province is one of the regions with the greatest number of species. The unique natural and geographic advantages provide an excellent environment for fungal growth. This study collected and isolated saprobic hyphomycetes associated with dead bamboo in Yunnan Province, China. Based on detailed morphological comparisons and multi‐locus phylogenetic analyses of combined LSU, ITS,

sequence data, the new isolates are introduced here as a novel species,
Hyalinostachys dehongensis
in the family Stachybotryaceae of Ascomycota. A complete description, morphological illustrations, and phylogenetic analysis results for the new species are provided. In addition, this species is introduced here as the second species since this genus was introduced in 2020.
Abstract During a survey of the taxonomy and diversity of saprobic fungi, fresh samples were collected from submerged decaying wood in freshwater habitats in Guizhou and Hainan Provinces, southern China. Phylogenetic analyses, based on LSU, ITS, SSU, tef1-α and rpb2 sequence data, together with morphological characteristics, support the introduction of two new species, Hyaloambispora aquaticasp. nov. and Paramirandina fusiseptatasp. nov. Detailed morphological descriptions, illustrations and multi-locus phylogenetic analyses are provided herein to support and substantiate the taxonomic placement of these newly-introduced taxa. Importantly, this study represents the first record of Hyaloambispora species from Guizhou Provinces, China, further expanding the known diversity of freshwater fungi in these regions.

A new species, Vararia subtropica, from Yunnan Province, SW China, is described and illustrated based on morphological characters and phylogenetic analyses. Vararia subtropica is characterized by the cream to buff hymenial surface, a dimitic hyphal system with generative hyphae with clamp connections, and cylindrical, slightly curved to allantoid basidiospores (7.1–11.3 × 2.7–5.2 µm). Sequences of ITS and nLSU were generated from the studied specimens, and phylogenetic analysis was performed with Maximum Likelihood and Bayesian Inference methods. The phylogenetic analysis indicated that the new species belongs to the genus Vararia and is the sister species of V. daweishanensis. A description, illustrations, and phylogenetic analysis results are provided. This discovery expands the known diversity of Vararia in subtropical Asia and improves our understanding of phylogenetic relationships within the genus.

Adustochaete is a small genus of wood-inhabiting basidiomycetes, currently comprising only six described species. A recent study has clarified the classification of this genus by combining phylogenetic analyses and morphological characteristics. However, the species diversity of Adustochaete in the high-altitude forests of Yunnan Province, China, has not been systematically studied. In the present study, detailed morphological characteristics and combined multi-locus phylogenetic analyses based on the internal transcribed spacers (ITS) and the large subunit (nrLSU) of the nuclear ribosomal DNA (rDNA) revealed a new species in Adustochaete, viz. A. sinensis. Comprehensive descriptions, micrographs, and phylogenetic analysis results are provided. The present study enriches the species diversity of Auriculariales in China, which should help protect and sustainably use fungal natural resources.
Abstract Freshwater and terrestrial ecosystems harbor a rich diversity of fungi, many of which remain poorly explored, particularly within the order Chaetothyriales. Four hyphomycetous isolates were obtained from freshwater and terrestrial habitats in Guizhou Province, China. Their morphological characteristics were examined, and multilocus phylogenetic analyses based on ITS, LSU, SSU, and tub2 were performed to clarify their taxonomic positions. Phylogenetic reconstruction indicated that the isolates represent two distinct species within Veronaea (Herpotrichiellaceae, Chaetothyriales), which are herein described as V. guizhouensis and V. terrestris. Comprehensive descriptions, illustrations, and morphological comparisons with related taxa are provided. These findings expand the known diversity of Veronaea and underscore the significance of freshwater and terrestrial woody substrates as reservoirs of novel fungal taxa.

Abstract Surveys of Xylariales fungi conducted in southwestern China resulted in the collection of several specimens from Yunnan and Guizhou Provinces. Morphological examination, together with multi-locus phylogenetic analyses based on combined ITS, LSU, rpb2, and tub2 sequence data, revealed that these specimens represent two previously undescribed species within Minuticlypeus and Paravamsapriya. These are introduced here as Minuticlypeus zunyiensissp. nov. and Paravamsapriya yunnanensissp. nov. Detailed morphological descriptions, illustrations, and phylogenetic trees clearly delineate these taxa, highlighting their distinct affiliations with existing species.

Dictyosporium sichuanense is described as a new species collected from submerged decaying twigs of Malus domestica (Rosaceae) in Sichuan Province, China. The species was identified using an integrative approach that combined morphological observations with molecular phylogenetic analyses. Phylogenetic relationships were inferred from a combined dataset of the ITS, LSU, and tef1-α loci using maximum likelihood and Bayesian inference. The new isolate was placed within a well-supported clade as the sister taxon to Dictyosporium oilvaceosporum and was separated from other Dictyosporium species. Its morphological characteristics further support its designation as a novel species. Morphologically, the new species differs from D. olivaceosporum by its dark black to olivaceous-brown conidia, composed of 15–32 cells arranged in 4–5 rows, and lacking conidial appendages. A detailed description, illustration, and a morphological comparison with closely related taxa are provided.
