Abstract

A new poroid wood-inhabiting fungal species, Cinereomyces fimbriatus sp. nov., is proposed based on morphological and molecular characteristics. The species is characterized by resupinate, brittle basidiomata with cream pore surface, a dimitic hyphal system with clamped generative hyphae, broad allantoid, hyaline, thin-walled, smooth basidiospores (3.6–4.6 × 0.8–1.1 µm). The internal transcribed spacer (ITS) region of nuclear ribosomal RNA gene sequences of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and bayesian inference methods. The phylogenetic analysis based on ITS sequences showed that C. fimbriatus formed a monophyletic lineage with strong supports (100% BS, 100% BT, 1.00 BPP) sister to C. lindbladii.
