A new white-rot corticioid wood-inhabiting fungal genus and species, Flavodontia rosea , collected from subtropical Yunnan, China, is proposed based on morphological and molecular evidence. Flavodontia is characterized by annual, resupinate basidiomes with a pink hymenial surface, a monomitic hyphal system with generative hyphae bearing simple septa, and ellipsoid basidiospores with thin hyaline smooth walls. Phylogenetic analyses of ITS and ITS + LSU nuclear RNA gene regions showed that Flavodontia formed a distinct, monophyletic lineage within a subclade that includes Flavodon and Irpex.
