LICHALP

Stereocaulon incrustatum Flörke

Syn.: Stereocaulon abduanum Anzi, Stereocaulon incrustatum Flörke var. abduanum (Anzi) Frey

Lichenised.

Substrate: acidic soil (mostly on siliceous substrata)

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) 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: an arctic-alpine to boreal-montane, circumpolar lichen found on mineral, nutrient-poor soil, in Pinus-woodlands, in the vicinity of glaciers and by rivers, with optimum near treeline.
