Lichens of South Africa

The Lichen species of South Africa as per
Alan M. Fryday 2015. A new checklist of lichenised, lichenicolous and allied fungi reported from South Africa Bothalia; Vol 45. doi: 10.4102/abc.v45i1.148
has been added to https://www.inaturalist.org/check_lists/1666357-Lichens-of-South-Africa

The current list includes 1750 taxa in 260 genera from mainland South Africa, with an additional 100 species and 23 genera from the sub-Antarctic Prince Edward Islands, which are treated separately. ... It is estimated that, when fully explored, the lichen biota of South Africa will consist of somewhere between 2500 and 3000 taxa.

High Altitude Lichens

From http://nhm2.uio.no/botanisk/lav/RLL/PDF1/R456.pdf
Lichens at high altitudes in Southern Africa O. Almborn 1987

Abstract:
It is still premature to present a detailed survey of the lichen biogeography of southern Africa but some patterns may be distinguished. The montane species (more or less corresponding to the alpine species of the Northern Hemisphere) form a fairly large group. They occur mainly at high altitudes; usually about 1000 m and are saxicolous or terricolous. A number of the montane species are endemics. Others also occur in the central African mountains. Species known from high mountains in southern Africa and also from southern America or Australia/New Zealand are of special interest to the phytogeographer; and may be relicts from the ancient Gondwana
This deals with the species listed below; with maps.

Some key points:
South Africa has a few cosmopolitan lichen species; for instance;

  • Candelaria concolor * Lobaria pulmonaria * Peltigera canina * Xanthoria parietina On the other hand; many species well known from the Northern Hemisphere are absent:
    Cetraria islandica; Cladina rangiferina; Evernia prunastri; Pseudevernia furfuracee; Parmelia saxatilis and Parmelia sulcata
    There are also many endemic species; such as

  • Combea mollusca * Roccella hypomecha * Roccellina capensis (Dirina capensis)
  • Teloschistes capensis * Xanthodactylon flammeum (Xanthoria flammeum)
  • Xanthomaculina hottentotta (Omphalodium hottentotta Or Parmelia hottentotta)
    It must be emphasized; however; that the lichens; like other groups of cryptogams; have few equivalents to the high number of endemic families; genera and species known from the phanerogamic flora.
