LICHALP

Acarospora admissa (Nyl.) Kullh.

Syn.: Lecanora admissa Nyl.

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: similar to A. nitrophila, but thallus squamules with wavy-crenulate, mostly black margins; in the study area so far only reported from the Western Alps (France).
