ABSTRACT=<p>An in-depth study of the phylogeny and taxonomy of the corticioid genus <italic>Phlebiopsis</italic> (Phanerochaetaceae) was conducted. Phylogenetic analyses of the ITS1-5.8S-ITS2 and nrLSU sequences demonstrated that <italic>Phlebiopsis</italic> is a strongly supported clade which is distinct from its sister clades of <italic>Phaeophlebiopsis</italic>, <italic>Hapalopilus</italic>, and <italic>Rhizochaete</italic>. Two genera, <italic>Australohydnum</italic> and <italic>Hjortstamia</italic>, are reduced to synonyms under <italic>Phlebiopsis</italic> as generic type species <italic>A. griseofuscescens</italic> and <italic>H. friesii</italic>, respectively, are embedded in the <italic>Phlebiopsis</italic> clade. Twenty-four lineages are resolved in the ITS phylogenetic tree of <italic>Phlebiopsis</italic>, including six new taxa, viz. <italic>P. albescens</italic>, <italic>P. brunnea</italic>, <italic>P. cylindrospora</italic>, <italic>P. magnicystidiata</italic>, <italic>P. membranacea</italic> and <italic>P. sinensis</italic>, from Sri Lanka and China. Five new combinations, viz. <italic>Phaeophlebiopsis mussooriensis</italic>, <italic>Phlebiopsis bambusicola</italic>, <italic>P. dregeana</italic>, <italic>P. griseofuscescens</italic> and <italic>P. novae-granatae</italic>, are proposed. <italic>Phlebiopsis crassa</italic> is a morphological species complex with three distinct lineages. <italic>Phlebiopsis lamprocystidiata</italic> is determined to be a later synonym of <italic>P. darjeelingensis</italic>. The new taxa are described, illustrated, and compared and contrasted to morphologically similar species. An emended description of <italic>Phlebiopsis</italic> is provided along with an identification key to 27 accepted species.</p>
