ABSTRACT=<p>The species diversity, taxonomy, and phylogeny of five corticioid genera of Phanerochaetaceae, namely, <italic>Hyphodermella, Roseograndinia, Phlebiopsis, Rhizochaete</italic>, and <italic>Phanerochaete</italic>, in East Asia are studied by using the morphological and molecular methods. Phylogenetic analyses were performed separately for the <italic>Donkia, Phlebiopsis, Rhizochaete</italic>, and <italic>Phanerochaete</italic> clades based on ITS1-5.8S-ITS2 and nrLSU sequence data. In total, seven new species were found, two new combinations are suggested, and a new name is proposed. In the <italic>Donkia</italic> clade, <italic>Hyphodermella</italic> sensu stricto was strongly supported with two new lineages, namely <italic>H. laevigata</italic> and <italic>H. tropica</italic>, which were recovered. <italic>Hyphodermella aurantiaca</italic> and <italic>H. zixishanensis</italic> are members of <italic>Roseograndinia</italic>, while <italic>R. jilinensis</italic> is proved to be a later synonym of <italic>H. aurantiaca</italic>. In the <italic>Phlebiopsis</italic> clade, <italic>P. cana</italic> sp. nov. was found on the bamboo from tropical Asia. In the <italic>Rhizochaete</italic> clade, four new species, <italic>R. nakasoneae, R. subradicata, R. terrestris</italic>, and <italic>R. yunnanensis</italic> were recovered based mainly on molecular analyses. In the <italic>Phanerochaete</italic> clade, <italic>P. subsanguinea</italic> nom. nov. is proposed to replace <italic>Phanerochaete rhizomorpha</italic> C.L. Zhao &amp; D.Q. Wang, which is an invalid name because it was published after <italic>Phanerochaete rhizomorpha</italic> C.C. Chen, Sheng H. Wu &amp; S.H. He, representing another species. Descriptions and illustrations are provided for the new species, and discussions are given for new taxa and names. Identification keys to <italic>Hyphodermella</italic> species worldwide and <italic>Rhizochaete</italic> species in China are given separately.</p>
