Aspicilia simoensis Räsänen

Syn.: Lecanora bahusiensis H. Magn., Lecanora isidiata (H. Magn.) H. Magn., Lecanora simoensis (Räsänen) Zahlbr., Lecanora simoensis (Räsänen) Zahlbr. var. isidiata H. Magn., Sagedia simoensis (Räsänen) A. Nordin, Savić & Tibell

Lichenised.

Substrate: siliceous rocks, intermediate rocks (such as calciferous schists)

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: a mostly sterile species with an areolate thallus reacting K+ red; based on a type from Finland and described as sorediate from the beginning; populations in the Alps have dense clusters of isidia later breaking down into soredia-like propagules (fitting Lecanora simoensis var. isidiata H. Magn.); most frequent on siliceous boulders visited by birds, widespread in the Alps.
