传统上，黑孢菌包括那些具有长颈和薄的、浅色的包被、渐逝的子囊和单细胞的、棕色的子囊孢子（有或没有定向）的真菌。类似的真菌与无孔子囊被放置在Microthecium Corda。近年来，有一种倾向，即评价是否存在小孔的意义不大（Von Arx，1973; Cailleux，1971; Krug等人，1983年）。这导致小囊菌属与黑孢菌属同义（Von Arx，1973; Cannon and霍克斯沃思，1982）。Doguet（1955）对黑孢菌属进行了研究，而Udagawa和Cain（1969）以及霍克斯沃思和Udagawa（1977）对小囊壳菌属进行了研究。更多的物种已被添加到这两个分类群中（例如Morinaga等人，1978年; Udagawa和Takada，1974年）。Von Arx（1981）指出Sphaerodes Clem.可用于那些具有明显孢子的物种，这些孢子似乎代表了一个系统发育单位。同时Krug和Jeng（1979）将Pteridiosperma（蕨类植物属）描述为不一致的种，而Rhytidospora（脉孢属）则被Jeng和Cain（1977）描述为该复合体中的另一个异常成分。Cannon和霍克斯沃思（1982）在处理英国分类群时，重新评价了黑孢菌属与相关属的关系。这导致了几个新属的建立，其中一个是Cannon & Hawksw。在研究从热带地区分离的真菌时，
Traditionally Melanospora Corda included those fungi with perithecial ascomata possessing long necks and a thin, pale-colored peridium, evanescent asci, and one-celled, brown ascospores with or without ornamentation. Similar fungi with non-ostiolate ascomata were placed in Microthecium Corda. In recent years there has been a tendency to evaluate the presence or absence of an ostiole as being of minor significance (Von Arx, 1973; Cailleux, 1971; Krug et al., 1983). This has resulted in Microthecium being synonymized with Melanospora (Von Arx, 1973; Cannon and Hawksworth, 1982). Melanospora was treated by Doguet (1955) while Microthecium has been considered by Udagawa and Cain (1969) and Hawksworth and Udagawa (1977). Further species have been added to both taxa (e.g. Morinaga et al.,1978; Udagawa and Takada, 1974). Von Arx (1981) pointed out that Sphaerodes Clem. is available for those species with ornamented spores which appear to represent a phylogenetic unit. Meanwhile Krug and Jeng (1979) erected Pteridiosperma for some discordant species while Rhytidospora was described by Jeng and Cain (1977) for another abnormal element in this complex. Cannon and Hawksworth (1982), while treating the British taxa, reappraised the relationship of Melanospora with related genera. This resulted in the erection of several new genera, of which one was Persiciospora Cannon & Hawksw. While studying fungi isolated from tropical
