Four new fungi from Xizang in southwest China, Calocera ramaria, Ceraceomyces rhizomorphus, Leptosporomyces linzhiensis, and Ramaria xizangensis are described and illustrated based on the morphological and molecular evidence. Calocera ramaria is characterized by the ramal and bright orange basidiomata, a monomitic hyphal system with simple septa generative hyphae, usually 4-septate basidiospores; Ceraceomyces rhizomorphus is characterized by the cream to yellowish basidiomata with rhizomorphs, cylindrical basidiospores; Leptosporomyces linzhiensis is characterized by white with pink basidiomata, cylindrical to oblong ellipsoid basidiospores; Ramaria xizangensis is characterized by flesh pink basidiomata, branched dichotomously in 4–5 ranks, a monomitic hyphal system with clamped generative hyphae, ellipsoid to cylindrical and densely warted basidiospores.
