Four epitypes and three new species of Amanita (Amanitaceae, Agaricales, Agaricomycetes, Basidiomycota) are described from Guineo-Congolian rainforests of Cameroon. Amanita echinulata, A. fulvopulverulenta, A. robusta, and A. bingensis are epitypified based on collections that are the first since the species were described nearly a century ago. Morphological features of the epitypes are described and enumerated. Amanita minima, Amanita luteolamellata, and A. goossensfontanae are described as new and added to the known macromycota of tropical Africa. Habit, habitat, and known distribution are provided for each species. Sequence data for the internal transcribed spacer (ITS) locus are provided for types and other collections of all taxa, and a molecular phylogenetic analysis across the genus Amanita corroborates morphology-based infrageneric placement for each.

几内亚-刚果雨林中的鹅膏菌：来自喀麦隆 Dja 生物圈保护区的表型和新物种

描述了喀麦隆几内亚-刚果雨林的四种表型和三种鹅膏菌新种（鹅膏菌科、伞菌目、伞菌目、担子菌门）。Amanita echinulata、A. fulvopulverulenta、A.robusta 和 A. bingensis 是基于近一个世纪前描述该物种以来首次收集的集合。描述并列举了表型的形态特征。Amanita minima、Amanita luteolalamellata 和 A. goossensfontanae 被描述为新的并添加到热带非洲已知的大型菌群中。为每个物种提供了习性、栖息地和已知分布。提供了所有分类群的类型和其他集合的内部转录间隔区 (ITS) 基因座的序列数据，
