A new wood-inhabiting fungus, Phlebia ailaoshanensis, is proposed based on a combination of morphological features and molecular evidence. The spccies is characterized by an annual growth habit, resupinate basidiocarps with tuberculate to phlebioid hy menial surface, a monomitic hyphal system with slightly thick-walled generative hyphae bearing simple septa. IKI-, CB- and ellipsoid, hyaline, thin-walled, smooth, IKI-, CB-basidiospores measuring as 5.7-8.5 x 3-4.3 mu m. Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and p1w logenetic analyses were performed with maximum likelihood, maximum parsimony and baycsian inference methods. The phylogenctic analyses based on molecular data of ITS+IESU sequences showed that P. ailaoshanensis belonged to the Meruliaceae and nested into the phlebioid Glade. Further investigation was obtained for more representative taxa in the Phlebia based on ITS+nLSU sequences, in which the result demonstrated that the species P. ailaoshanensis formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP) and then grouped with P. acanthocystis, P. chrysocreas, P. ludoviciana, P. subcretacea and P. uda.
