LICHALP

Rinodina zwackhiana (Kremp.) Körb.

Syn.: Lecanora zwackhiana Kremp., Rinodina murorum B. de Lesd., Rinodina transsylvanica (Nyl.) H. Olivier, Rinodina violascens H. Magn.

Lichenised.

Substrate: calciferous rocks

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)

Note: a mainly mild-temperate lichen found on steeply inclined to slightly underhanging surfaces of calcareous rocks, including walls, sometimes a juvenile parasite on other lichens; probably more widespread, but much overlooked in the Alps.
