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