LICHALP

Aspicilia rosulata Körb.

Syn.: Aspicilia proserpens (Nyl.) Hue

Lichenised. Poorly known taxon.

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

Altitudinal range: from the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers) to the nival belt (above the lower limit of perennial snow and glaciers)

Note: a fertile species with a grey to blackish-brown, effigurate thallus and finally sessile apothecia; based on a type from Franz Josef Land, where it grows on periodically inundated boulders; identity and uniformity of records from the Alps are uncertain, because the secondary chemistry is apparently not uniform, and the ecology is different (on exposed, usually steep rock faces).
