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.

Most known brown rot–producing species of Polyporales belong to the so-called "Antrodia clade" that largely consists of poroid species. In this study, we use three genetic markers to revise Antrodia s. str., the core group of this clade. We show that a corticioid species with a smooth hymenophore, Phlebia griseoflavescens, belongs to Antrodia s. str. Accordingly, we revise the generic concept of Antrodia s. str. to accommodate this species and two recently described poroid taxa, A. tenerifensis and A. multiformis. In addition, we describe two new poroid species within Antrodia s. str., A. latebrosa from Africa and A. peregrina from East Asia, and provide new documentation for the Southeast Asian species A. parvula based on recent collections from the type location.

A rare boreonemoral species, Phlebia tremelloidea (Bres.) Parmasto was characterized morphologically and ecologically basing on Russian material. The specified description of the species was given. The variability of top lamprocystidia, basidia and basidiospores of the fungus was revealed. An abhymenial, medullar, and subhymenial strates of the basidiocarp were characterized. The relationships between developmental environments and morphology of the fungus were discussed.
