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

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.

Automated summary

This study describes four epitypes and three new species of Amanita from Guineo-Congolian rainforests in Cameroon. Four epitypes were based on collections dating back nearly a century, while three new species were added to the known macromycota of tropical Africa. Sequence data for the internal transcribed spacer (ITS) locus were provided for all taxa, and a molecular phylogenetic analysis across the genus Amanita confirmed morphology-based infrageneric placement for each species.
