LICHALP

Caloplaca rubelliana (Ach.) Lojka

Syn.: Callopisma rubellianum (Ach.) A. Massal., Lecanora rubelliana Ach.

Lichenised.

Substrate: siliceous 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 warm-temperate to subtropical, widespread lichen found on hard, basic siliceous rocks (especially basalt), often with Acarospora sulphurata; apparently more frequent in the Southern and Western Alps.
