Lichenised.

Substrate: calciferous soil,

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: an often overlooked terricolous lichen found on calciferous soil and calcicolous mosses, which seems to be most common in the submediterranean belt; apparently more frequent in the Western and Southern Alps.
