Abstract:
:Two new species of Phylloporus from Bangladesh forests dominated by Shorea robusta are described and illustrated, based on morphological and molecular phylogenetic evidence. Phylloporus attenuatus is characterized by its wine-red to brownish-red pilei, decurrent lamellae that stain blue, downwards tapering stipe, a trichodermium pileipellis, and ellipsoidal-ovoid to ellipsoidal basidiospores (7-8 × 4-5 µm). Phylloporus catenulatus is characterized by its small-sized basidiomata with reddish-brown pilei, narrowly decurrent with distant lamellae that stain blue, a subepithelium pileipellis, and ellipsoidal to ellipsoidal-ovoid basidiospores (8-9.5 × 4-5 µm). Both new species of Phylloporus are distinctive from any known taxa based on phylogenetic analyses of partial sequences of the nuc rDNA internal transcribed spacer (ITS; including ITS1-ITS2 but not 5.8S) region, partial sequence of nuclear ribosomal large subunit (28S) domains D1 and D2, and translation elongation factor 1-α (TEF1α). Both species are compared with phenotypically similar taxa and illustrated with line drawings and photographs. A key to the species of Phylloporus known from Bangladesh is provided.
