    Abstract

    The available collections of the lichen genus Pertusaria from the eastern parts of Central Africa (mainly in the Albertine Rift in Congo/Kivu. Burundi and Rwanda) and Western Kenya yielded 21 species. Four are described as new for science: Pertusaria fosseyae. P. kinigiensis. P. krogiae and P. lambinonii. The following species are new reports for Africa: P. commutata. P. maritima. P. melanostoma. P. mesotropa. P. microstoma. P. orarensis. P. pilosula. P. rigida. P. scaberula. P. subplanaica. P. subrigida. P. valliculata. and P. verruculifera. The following are reduced into synonymy: Pertusaria amboimensis with P. leioplacella. P. macrostomoides. P. prolifera and P. norstictica with P. endoxantha. P. kahuziensis with P. velata. and P. robsonii with P. limbata. P. aberdarensis is suspected to be a synonym of P. rigida. An identification key to all species is provided. The type collections of three further species described from Africa have been examined: P. kigomensis. P. regenerans and P. rhodesica.
