Lichenised.
Substrate: calciferous rocks
Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: a temperate, somehow subcontinental species found on calciferous substrata, especially on mortar walls; not common everywhere in the Alps, perhaps because of its subcontinental character, but abundant, and locally extremely abundant in some dry valleys of the Alps, mostly on walls in small villages, much rarer in natural habitats.
