Molecular Phylogeny and Morphology Reveal Four New Species of (Bolbitiaceae, Agaricales) from the Qinghai-Xizang Plateau, China.

The Qinghai-Xizang Plateau, known for its high altitude, geological history of plate collision, crustal uplift, and special ecology factors, provides an ideal environment for studying fungal biodiversity in extreme environmental conditions. Some species within the , containing secondary metabolites such as psilocybin, phallotoxins, and amatoxins, have potential medicinal value for treating psychiatric disorders and for use in drug development. This study investigates (Bolbitiaceae, Agaricales) on the Plateau, based on specimens collected over the past decade, using morphological and molecular phylogenetic analyses.

New and species (Pleosporales, Ascomycota) from spp. in China.

Saprobic fungi are known for their critical role in decomposition and nutrient cycling. The study of saprobic fungi is equally important, as it helps in understanding their ecological roles and identifying their hidden diversity. This study focused on saprobic fungi on , which is poorly studied compared to economically important hosts like coffee, tea, and rubber.

Assigning (genus ) to Pseudoberkleasmiaceae (Dothideomycetes, Pleosporomycetidae, Pleosporales) and introducing as a novel species.

species are dematiaceous hyphomycetes that are characterised by acropleurogenous, dictyoseptate, campanulate or cheiroid, and brown to dark brown conidia that are composed of several layers of cells radiating from a protuberant basal cell, and mostly seen with appendages arising from the apical cells. The genus was introduced based on morphology to accommodate five of the six species that exhibited holoblastic conidial ontogeny. was referred to as Ascomycota genus as it was challenging to resolve its taxonomic placement based solely on the available morphological data (no DNA sequence data was previously available).

Additions to Dictyosporiaceae: comb. et gen. nov., Two New Species and Four New Host Records from Medicinal Plants in Southwestern China.

Medicinal plants serve as vital resources for preventing and treating diseases, with their flowers, fruits, leaves, roots, or entire plants being utilized in the pharmaceutical industry or as direct therapeutic agents. During our investigation of microfungi associated with medicinal plants in Guizhou and Sichuan Provinces, China, several asexual and sexual fungal morphs were collected. Multi-locus phylogenetic analysis based on combined ITS, LSU, SSU and datasets revealed that these taxa are related to the family Dictyosporiaceae.

Multigene phylogeny, taxonomy, and potential biological properties of and species (Roussoellaceae, Dothideomycetes) from Asteraceae weeds in northern Thailand.

In our study, dead stems of two Asteraceae species (weeds) were collected from northern Thailand. Both morphology and multigene phylogeny were used to determine the identity of the taxa. Maximum likelihood and Bayesian inference analyses of combined LSU, SSU, ITS, and data revealed two new species , and with one new host record of .
