ABSTRACT
Taxonomic and phylogenetic studies on Datronia were carried out. Phylogeny based on ITS, nLSU and RBP2 regions revealed that Datronia in current sense includes species belonging to three distantly related clades in polypores. The Datronia in a restricted sense is proposed for the clade including the type species D. mollis and D. stereoides. Neodatronia gen. nov. was proposed for two new resupinate species, N. gaoligongensis and N. sinensis. Species of Neodatronia differ from Datronia s.s. by their resupinate basidiomes, moderately to frequently branched skeletal hyphae in subiculum. Datroniella gen. nov., typified by D. scutellata was proposed for species in the other clade. Four new species of Datroniella, D. melanocarpa, D. subtropica, D. tibetica and D. tropica, were identified. Species of Datroniella differ from Datronia s.s. by their moderately to frequently branched skeletal hyphae in context and absence of dendrohyphidia. While, differentiate from Neodatronia by their small pileate, effused-reflexed or rarely resupinate basidiomes and absence of dendrohyphidia. Illustrated descriptions of the new species and two new genera are provided. The main morphological differences between Datronia, Datroniella, Neodatronia and related genera are discussed, identification keys to related genera and species in each genus are provided.

Mentions: Neodatronia was formed by two resupinate species: N. gaoligongensis and N. sinensis with strong support (MP = 100 %, BPP = 1.00, Fig. 1), then it clustered with Datronia s.s. Species in both genera share a dimitic hyphal system with clamped generative hyphae, thin-walled basidiospores and presence of dendrohyphidia (Núñez & Ryvarden 2001, Table 2). But Neodatronia differs from Datronia s.s. by producing distinct resupinate basidiomes, moderately to frequently branched skeletal hyphae in subiculum (Fig. 3, 8, 9, 10, 11, Table 2, 3).
