69 lichen species are recorded as new to Rwanda. Catillaria alba, Chaenotheca stemonea and Parmotrema neotropicum are new to Africa, Caloplaca ferruginea to tropical Africa. Cetrariastrum vexans previously has only been reported from Mt Kenya; for Ramalina roesleri it is the second known locality in Africa. A short history of the lichenological exploration as well as an overview of the vegetation of Rwanda is presented.
