LICHALP

Protoblastenia incrustans (DC.) J. Steiner var. coniasis (A. Massal.) Nimis

Syn.: Biatora coniasis A. Massal., Lecidea coniasis (A. Massal.) Lettau, Protoblastenia coniasis (A. Massal.) Poelt

Lichenised.

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

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 steeply inclined surfaces of more or less calciferous rocks near and above treeline; certainly more widespread throughout the Alps, but not common; this taxon is well worthy of further study.
