The Qinghai-Xizang Plateau (abbreviated as Q-X Plateau) is the world’s highest plateau, characterized by a Holarctic flora. The plateau and its surrounding mountainous areas cover two of the 34 world’s biodiversity hotspots. Former studies have shown that the diversity of fungal species on the plateau, especially that in the east-southeastern part, is remarkably high. In 2017, the Chinese government initiated the second scientific expedition to the Q-X Plateau. Supported by this comprehensive project, we conducted intensive fungal sampling on the Q-X Plateau and its surrounding areas, including the middle and southern parts of the Gaoligong Mountains, the Ailao Mountains, and the Yunnan-Guizhou Plateau. Ninety-two new and notable species of Basidiomycota are reported in this paper, based on 501 specimens and 1706 newly generated DNA sequences. These taxa involve 37 genera of seven orders, i.e., Agaricales, Auriculariales, Boletales, Cantharellales, Phallales, Polyporales, and Russulales, covering both Heterobasidiomycetes and Homobasidiomycetes. One new section, 64 new species, one new subspecies, two new varieties, one new combination, five new synonyms, and 11 new records to China, were documented. Ectomycorrhizal fungi account for two-thirds of the species, while the remaining ones are saprotrophic. Most specimens studied are from altitudes 2000–3700 m, in broad-leaved fagaceous forests, mixed forests with pines and fagaceous trees, and subalpine coniferous forests. Among ...
