摘要

根据形态学和分子生物学证据，提出了一个新的分布于云南亚热带地区的白腐类皮质木真菌属和种——玫瑰黄牙菌。Flavodontia的特征是具有粉红色处女膜表面的一年生复旋担子体，具有带有简单隔膜的生殖菌丝的单体菌丝系统，以及具有薄透明光滑壁的椭球状担孢子。ITS和ITS+LSU核RNA基因区的系统发育分析表明，Flavodonta在包括Flavodon和Irpex在内的亚群中形成了一个独特的单系谱系。

Flavodontia rosea gen. & sp. nov. from southwestern China

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.
