文摘

A new poroid wood-inhabiting fungal species, Ceriporiopsis kunmingensis sp. nov., is proposed based on morphological and molecular characters. The species is characterized by resupinate basidiocarps with pale cinnamon-buff to ochreous color when dry; generative hyphae unbranched and subparallel along the tubes; presence of hyphal ends; allantoid basidiospores, 4.5–5 × 1.5–2 μm. The internal transcribed spacer (ITS) and large subunit (LSU) regions 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 molecular data of ITS + nLSU sequences showed that C. kunmingensis belonged to the phlebioid clade, formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP), and was closely related to Phlebia aurea, and then grouped with P. livida and P. subserialis. Both morphological and molecular characters confirmed the placement of the new species in Ceriporiopsis.
