Lichenised.

Substrate: calciferous soil, living mosses

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the nival belt (above the lower limit of perennial snow and glaciers)

Note: an extremely polymorphic and ecologically wide-ranging species, certainly the most common of the genus in the Alps; it is a widespread holarctic, almost cosmopolitan lichen found on calciferous or base-rich siliceous soil in open habitats (e.g. in dry grasslands), on consolidating sand dunes and on terricolous bryophytes, more rarely directly on rock, often found also in disturbed habitats such as track sides in urban settlements.
