在非洲，对Inocybaceae的研究很少。在这里，我们描述的第一个物种的属Mallocybe从西非和赞比亚的林地占主导地位的外生菌根树的豆科和叶下珠科。新种M. africana的特征在于橙棕色的子实体、具原纤维的菌盖、向基部渐缩的柄和大的椭圆形担孢子。它类似于许多北温带和南温带的马鹿菇属物种，但与东南亚热带物种马鹿菇（M.勘误表。M. Africana广泛分布于西非（贝宁、多哥、布基纳法索和象牙海岸），延伸至赞比亚的东南非洲。基于5.8S rDNA、nLSU和RPB 2序列的系统发育分析证实M. Africana是Mallocybe的一部分。一个完整的形态描述和插图，包括照片和线条画，提出。
The family Inocybaceae has been poorly studied in Africa. Here we describe the first species of the genus Mallocybe from West African and Zambian woodlands dominated by ectomycorrhizal trees of Fabaceae and Phyllanthaceae. The new species M. africana is characterized by orange-brown fruitbodies, a fibrillose pileus, a stipe tapered towards the base and large ellipsoid basidiospores. It resembles many north and south temperate species of Mallocybe but is most closely related to the southeast Asian tropical species, M. errata. M. africana is widely distributed in West Africa (Benin, Togo, Burkina Faso and Ivory Coast) extending to South-eastern Africa in Zambia. Phylogenetic analyses based on 5.8S rDNA, nLSU and RPB2 sequence data confirm that M. africana is nested within Mallocybe. A complete morphological description and illustrations, including photographs and line drawings, are presented.
