Revision of the lichen genus Teloschistes in central and southern Africa

Abstract

Nine species of Teloschisies are recorded from the area and details of their morphology (including considerable ecotypic variation) and distribution are given. All species are illustrated. All relevant type specimens were examined. Four species (T. chry‐sophthalmus, T. exilis, T. flavicans and T. hypoglaucus) are common in this part of Africa and are also widely distributed elsewhere. T. perrugosus, whose taxonomy has been revised, seems to be endemic to central and southern Africa. T. capensis and T. puber are well‐defined endemics of the Atlantic coast in South Africa and Namibia, whereas T. chrysocarpoides occurs in Namibia only. T. pulvinaris, now established as a distinct species, is known only from the type locality in Cape Province. Copyright © 1989, Wiley Blackwell. All rights reserved
