Four new foliicolous lichen species are described from the Ivory Coast (Tropical West Africa): Bapalmuia ivoriensis sp. nov., Chroodiscus africanus sp. nov., C. verrucosus sp. nov., and Lasioloma inexspectatum sp. nov. In addition, the new combination Calenia inconspicua comb, nova [Bas.: Heterothecium inconspicuum] is introduced. Lasioloma inexspectatum is the first species in the genus characterized by transversely septate ascospores and provides additional evidence for phylogenetic lines regarding the evolution of ascospore types in the lichen family Ectolechiaceae. In addition, 61 new records for the Ivory Coast and seven for Guinea are presented, increasing the number of species known in these areas to 161 and 124, respectively. Five species are new for tropical Africa, and six new for the Paleotropics. Further taxonomical and ecogeographical notes on the foliicolous lichen flora of tropical West Africa are provided.
