The African genus Trichoscypha is revised for Upper Guinea (a similar revision for Lower Guinea will follow). Fourteen species are recognized for the area, five of which are described as new. Ten species are confined to Upper Guinea, and the remaining four species also occur in Lower Guinea. A key to the species is given and their distributions are mapped. The new species are illustrated, as are the male and the female flowers of the other species, when known.
