LICHALP

Aspicilia supertegens Arnold

Syn.: Aspicilia prinii B. de Lesd., Lecanora leucostoma H. Magn., Lecanora supertegens (Arnold) Zahlbr.

Lichenised.

Substrate:

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: a boreal-montane to arctic-alpine, perhaps circumpolar, variable lichen found on lime-free but base-rich rocks, often on mica-schist in humid situations (near brooks, melting snow, etc.).
