在形态和系统发育研究的基础上，描述并图示了日本博宁群岛的一新种。本种的特征是无梗担子果具有蹄状菌盖，菌盖表面有黑色结皮，气孔4E6/mm，二分生菌丝系统由夹持的生殖菌丝和嗜氰骨结合菌丝组成，具有或不具有糊精反应，圆柱形担孢子5.5E7。52e3μm，管壁和孔面附近有囊泡。对其他黑皮病物种的正品标本的形态观察表明，该属在囊泡的形状和大小方面是可变的。菌盖表面的黑色结皮由栅栏和高度凝集的菌丝组成，这是黑皮病区别于近缘属的一个独特的诊断形态特征。目前已知于博宁群岛限制区域的博宁黑霉菌，由于入侵树爪哇木霉，可能受到当地环境退化的威胁。©2019日本真菌学会。爱思唯尔BV出版，版权所有。
Melanoderma boninense is described and illustrated as a new species from the Bonin Islands, Japan, on the basis of morphological and phylogenetic investigations. This species is characterized by sessile basidiocarps with an ungulate pileus, a black crust on the pileus surface, pores 4e6/mm, a dimitic hyphal system comprising clamped generative hyphae and cyanophilous skeletal binding hyphae with or without a dextrinoid reaction, cylindrical basidiospores measuring 5.5 e7. 5 Â 2e3 μm, and cystidioles on the sides of tubes and near the pore surface. Morphological examination of authentic specimens of other Melanoderma species revealed that the genus is variable in terms of the shape and size of cystidioles. A black crust on the pileus surface composed of palisade and highly agglutinated hyphae is a distinctive diagnostic morphological feature of Melanoderma that differentiates it from allied genera. Melanoderma boninense, which is currently known from a restricted area of the Bonin Islands, is potentially threatened by environmental reduction of the type locality due to the invasive tree Bischofia javanica.© 2019 The Mycological Society of Japan.
