Species of the genusPhylloporusin China were investigated based on morphology and molecular phylogenetic analysis of a three-locus (nrLSU, ITS andtef-1a) DNA sequence dataset. Twenty-one phylogenetic species were recognized among the studied collections. Seven of them are described as new:P. brunneiceps,P. imbricatus,P. maculatus,P. pachycystidiatus,P. rubeolus,P. rubrosquamosus, andP. yunnanensis. In addition, four of them correspond with the previous morphology-based taxa:P. bellus,P. luxiensis,P. parvisporus, andP. rufescens. The remaining ten phylogenetic species were not described due to the paucity of the materials. A key to the Chinese morphologically recognizable taxa was provided. A preliminary biogeographical analysis showed that (1)Pylloporusspecies in East Asia and Southeast Asia are mostly closely related, (2) species pairs or closely related species ofPhylloporusbetween East Asia and North/Central America are relatively common, and (3) the biogeographic relationship ofPhylloporusbetween East Asia and Europe was supported by only a single species pair. Unexpectedly, no taxa common either to both Europe and East Asia, or to both East Asia and North/Central America, were uncovered. Clades look to have taxa from both sides of the Pacific and Europe/Asia though.
