LICHALP

Lecanora orosthea (Ach.) Ach.

Syn.: Biatora orosthea (Ach.) W. Mann, Lecanora sulphurea (Hoffm.) Ach. var. orosthea (Ach.) Flagey, Lecidea orosthea (Ach.) Ach., Lichen orostheus Ach., Zeora orosthea (Ach.) Flot.

Lichenised.

Substrate: siliceous rocks

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) 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 vertical or underhanging surfaces of siliceous rocks protected from rain in upland areas; certainly more widespread in the Alps.
