Lichenised.

Substrate: calciferous rocks, intermediate rocks (such as calciferous schists), living mosses, plant debris, lignum

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: a holarctic, subtropical to arctic-alpine, almost cosmopolitan species found on a wide variety of calciferous substrata, from limestone and dolomite to mortar, asbestos-cement and concrete, exceptionally on eutrophicated and dusty lignum and bark, sometimes starting the life-cycle on other crustose lichens; widespread and common throughout the Alps.
