Vanderbylia cinnamomea sp. nov. from southwestern China

Abstract

Vanderbylia cinnamomea is proposed as a new wood-inhabiting polypore species based on morphological characters supported by phylogenetic analysis. The species is characterized by an annual, pileate basidiocarp, a brown to black pileal surface, an olivaceous buff to smoke grey pore surface, a dimitic hyphal system with clamped generative hyphae, and subglobose to amygdaliform, hyaline, thick-walled, smooth, dextrinoid, and cyanophilous basidiospores. ITS+nLSU sequence analyses place V. cinnamomea in Vanderbylia within a subclade with a high support (100% BS, 100% BP, 1.00 BPP) sister to a subclade comprising V. fraxinea and V. robiniophila.
