Lichenised. Poorly known taxon.

Substrate: calciferous rocks, 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: on calcareous soil, most often in fissures of calcareous rocks. E. pusillum in the sense of most European authors is heterogeneous, and perhaps could be subdivided into several species; widespread throughout the Alps.
