本文报道采自海南和湖南的一个新属--黑皮菌属（多孔菌目，担子菌门），并以黑皮菌M.小果。该新种的特征为：多年生，具菌毛至倒折的担子果，菌毛表面有黑色外壳，孔小而圆，菌丝系统为二分型，具夹紧的菌丝，骨骼菌丝为糊精状和嗜氰性，担孢子为圆柱形，薄壁，非淀粉状，非糊精状和不嗜氰性，顶部有包囊，缺乏菌丝栓和树状菌丝。并与Australoporus、Datronia、Dichomitus、Megasporoporia和Perenniporia等相关属进行了比较。rDNA序列分析支持黑皮菌属是一个与Vanderbylia密切相关的单系分支。
A new genus Melanoderma (Polyporales, Basidiomycota), collected from Hainan and Hunan Provinces in southern China, is proposed and typified by M. microcarpum. The new species is characterized by a perennial habit, pileate to effused-reflexed basidiocarps with a black crust at the pileal surface, small round pores, a dimitic hyphal system with clamped generative hyphae, dextrinoid and cyanophilous skeletal hyphae, cylindrical, thin-walled, non-amyloid, non-dextrinoid and acyanophilous basidiospores, the presence of apically encrusted cystidia, and lack of both hyphal pegs and dendrohyphidia. The new genus is compared with related genera of Australoporus, Datronia, Dichomitus, Megasporoporia, and Perenniporia. rDNA sequence analysis supports Melanoderma as a monophyletic clade that is closely related to Vanderbylia.
