<i>Amanita</i> in the Guineo-Congolian rainforest: Epitypes and new species from the Dja Biosphere Reserve, Cameroon

Four epitypes and three new species of <i>Amanita</i> (Amanitaceae, Agaricales, Agaricomycetes, Basidiomycota) are described from Guineo-Congolian rainforests of Cameroon. <i>Amanita echinulata, A. fulvopulverulenta, A. robusta</i>, and <i>A. bingensis</i> 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. <i>Amanita minima, Amanita luteolamellata</i>, and <i>A. goossensfontanae</i> 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 <i>Amanita</i> corroborates morphology-based infrageneric placement for each.
