LICHALP

Lecanora caesiosora Poelt

Syn.: Lecanora cenisia Ach. var. soredians Suza, Lecanora soralifera H. Magn. non (Suza) Räsänen

Lichenised.

Substrate: siliceous 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 hard siliceous rocks in upland areas; very much overlooked, but certainly not common in the Alps.
