A new species, Candolleomyces yunnanensis, collected from Yunnan Province, China, is described based on morphological characteristics and molecular data. It is morphologically distinguished by its larger pileipellis cells, a pileus that is bronze brown (5E5) to yellowish brown (5E4) at the center and brownish grey (5E2) to birch grey (5C2) towards the margin, a fugacious veil, and the absence of pleurocystidia. Phylogenetic analyses of the nrITS, nrLSU, and tef-1α combined sequence confirm C. yunnanensis as a distinct member of Candolleomyces, forming a separate lineage from other Candolleomyces species.
