Physcia adscendens H. Olivier

Syn.: Parmelia stellaris (L.) Ach. var. adscendens Fr., Physcia ascendens Bitter

Lichenised.

Substrate: bark, lignum, calciferous rocks, siliceous rocks

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) 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 widespread holarctic lichen, one of the most common species of the genus throughout the Alps, mostly on isolated trees, but also on walls and eutrophicated calciferous rocks.
