Abstract

A new wood-inhabiting fungal species, Podoscypha yunnanensis sp. nov., is proposed based on morphological and molecular characters. The species is characterized by annual, gregarious basidiocarps with spathulate to flabelliform pilei, a dimitic hyphal system with clamped generative hyphae, caulocystidia cylindrical with an apex, and ellipsoid to subglobose basidiospores measuring 3–3.5(–4) × 2.5–3(–3.5) µm. The internal transcribed spacer (ITS) and the large subunit (LSU) regions of the 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 analyses based on molecular data of ITS sequences showed that P. yunnanensis belonged to the genus Podoscypha and was closely related to P. fulvonitens and P. mellissii. Phylogeny based on ITS+nLSU sequences demonstrated that the new species formed a monophyletic lineage with a high support (100% BS, 100% BP, 1.00 BPP).
