Taxonomy and phylogeny of phanerochaete sensu stricto (Polyporales, basidiomycota) with emphasis on chinese collections and descriptions of nine new species

Abstract

The taxonomy of Phanerochaete sensu stricto is studied herein by using both morphological and molecular methods. Phylogenetic analyses are based on a concatenated ITS1-5.8S-ITS2 and nrLSU sequence data of 50 taxa of Phanerochaete s.s. around the world. Among these are nine newly described and illustrated species-P. burdsallii, P. cinerea, P. hymenochaetoides, P. leptocystidiata, P. metuloidea, P. minor, P. sinensis, P. subrosea and P. yunnanensis. While P. burdsallii is from the U.S.A., the other new species were collected from China. In addition, nine species, P. bambucicola, P. citrinosanguinea, P. concrescens, P. cumulodentata, P. ericina, P. incarnata, P. livescens, P. magnoliae and P. taiwaniana are reported from mainland China for the first time. So far, 28 species of Phanerochaete s.s. from mainland China are confirmed by morphology and DNA sequence data. An identification key to all these species is presented. Phanerochaete fusca is determined to be a synonym of P. porostereoides.
