TL;DR

The previously underestimated diversity of hypogeous Boletales in China is underscore and the first Chinese record of R. sinoevadens is reported, a new species from China, and the first Chinese record of T. persicina is reported.

Abstract

Hypogeous Boletales are ectomycorrhizal fungi with sequestered hymenophores; some species are ecologically valuable as edible mushrooms. Despite their ecological and economical importance, the diversity of this group in China remains poorly understood. In this study, we performed phylogenetic analyses based on four loci (ITS, LSU, TEF1‐α , and RPB2 ) and detailed morphological examinations of specimens belonging to Rhizopogon (Rhizopogonaceae) and Turmalinea (Boletaceae). We describe and illustrate R. sinoevadens , a new species from China, and report the first Chinese record of T. persicina , a species originally described from Japan. These discoveries underscore the previously underestimated diversity of hypogeous Boletales in China and provide a foundation for future taxonomic and ecological studies.

Two new species of Oberwinklerozyma and Rosettozyma (Microbotryomycetes) from Yunnan, southwestern China

Oberwinklerozyma and Rosettozyma comprise a relatively small number of described species worldwide. Although several novel species from China have recently been reported, the species diversity of these two genera remains incompletely understood. In this study, two novel yeast species, Oberwinklerozyma jinghongens...

A New Species of Hyphoderma (Polyporales, Basidiomycota) From Southern China

We collected a wood‐inhabiting fungus of the genus Hyphoderma from a fallen Abies trunk in Sichuan Province, China. Morphological and molecular analyses using the ITS + nLSU dataset showed that this specimen represents a previously undescribed Hyphoderma species, which we designate as H. sichuanense . Hyphod...
