基于形态特征和系统发育分析，描述了一种新的多孔菌Skeletocutis subalbomarginata。其特征为多年生、反折至绒毛状担子果、每毫米8-10个小孔、二分形菌丝系统、由尖尖晶体包覆的生殖菌丝、橙棕色骨架菌丝、窄尿囊状担子孢子，尺寸为2.7-3.4*0.5-0.8mum。基于内部转录间隔区 (ITS) 区域和核大亚基 (nLSU) 核糖体 RNA 基因区域的系统发育分析表明，新物种嵌套在 Skeletocutis 进化枝内。此外，Piloporia 被视为 Skeletocutis 的同义词，以及三个新组合 Skeletocutis albomarginata (Zipp. ex Lev.) Rui Du & Y.C. Dai, Skeletocutis indica (Ganesh & Ryvarden) Rui Du & Y.C. Dai 和 Skeletocutis sajanensis (Parmasto) Rui Du & Y.C.戴，提议。
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*0.5-0.8mum. 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 Lev.) 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.
