Foliicolous lichen collections on Mount Kanga, Tanzania (East Africa)

Abstract

Abstract The Tanzanian Mt Kanga was at first visited by Tamas Pocs in 1987 when he collected foliicolous lichens in lowland rainforest between 800 and 900 m elevation and in submontane rainforest between 900 and 1,250 m. Later, in 1989 he returned there with participants of the Nguru Mts expedition, when the author collected further lichens including foliicolous ones in three different forest types (dry evergreen and semi-evergreen forest at 600–800 m, submontane rainforest at 850–1,200 m and rocky forest at 1,200–1,300 m). Altogether 37 species became known from the area. The comparison of collections revealed that submontane rainforests (including rocky forests) are the richest of the studied forest types in foliicolous lichens. Mt Kanga is characterised by rare species like Calopadia editae discovered by Antonin Vězda in material from Mt Kanga, described and validated in 2011 by Chaves and Lucking based on materials from Mt Kanga and Costa Rica. The new combination Brasilicia dimerelloides (Vězda) Fark...
