Cinereomyces wuliangshanensis sp. nov. from China

Abstract

A new poroid wood-inhabiting fungal species, Cinereomyces wuliangshanensis, is proposed based on morphological and molecular characters. The species is characterized by resupinate brittle basidiomata with a white pore surface, a dimitic hyphal system with clamped generative hyphae, and subglobose to broadly ellipsoid hyaline thin-walled smooth basidiospores (4.2–5.1 × 2.9–3.8 μm). Sequences were generated from the internal transcribed spacer (ITS) region of nuclear ribosomal RNA gene and phylogenetically analyzed using maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogeny strongly (100% BS, 100% BT, 1.00 BPP) supports C. wuliangshanensis in a monophyletic lineage grouping with C. lindbladii and a clade comprising Obba rivulosa and O. valdiviana.
