Caloplaca proteus Poelt

Syn.: Caloplaca cirrochroa (Ach.) Th. Fr. subsp. fulva (Körb.) Clauzade & Cl. Roux, Leproplaca proteus (Poelt) Arup, Frödén & Søchting, Physcia murorum auct. var. placibilis Kremp., Placodium pusillum (A.Massal) Anzi var. miniatum sensu Anzi

Lichenised.

Substrate: calciferous rocks

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: on steeply inclined to underhanging surfaces of compact, more or less calcareous rocks in rather sheltered situations, most frequent in warm-dry sites in the Alps.
