LICHALP

Aspicilia cacuminum (Müll. Arg.) Kernst.

Syn.: Lecanora cacuminum Müll. Arg.

Lichenised. Poorly known taxon.

Substrate: calciferous 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 high-alpine species with subeffigurate thallus margins, whose taxonomic value is in need of re-evaluation; the distribution is still insufficiently known.
