- Abstract
A new polypore, Skeletocutis subalbomarginata, is described based on morphological characteristics and phylogenetic analysis. It is characterized by perennial, effused-reflexed to pileate basidiocarps, small pores measuring 8-10 per mm, a dimitic hyphal system, encrusted generative hyphae by sharp-pointed crystals, orange brownish skeletal hyphae, narrowly allantoid basidiospores measuring 2.7-3.4×0.5-0.8μm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions indicated that the new species nested within the Skeletocutis clade. In addition, Piloporia is treated as a synonym of Skeletocutis, and three new combinations, Skeletocutis albomarginata (Zipp. ex Lév.) Rui Du & Y.C. Dai, Skeletocutis indica (Ganesh & Ryvarden) Rui Du & Y.C. Dai and Skeletocutis sajanensis (Parmasto) Rui Du & Y.C. Dai, are proposed.
