Substrate: calciferous rocks, intermediate rocks (such as calciferous schists), parasitic on other lichens

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the nival belt (above the lower limit of perennial snow and glaciers)
