Lichenised.

Substrate: calciferous rocks

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) 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: a species resembling P. dominans, but with smaller, narrowly ellipsoid ascospores with usually 5 transversal septa and occasionally a single incomplete longitudinal septum; on hard calciferous rocks in shaded and humid situations, often on pebbles, most frequent above treeline; widespread throughout the Alps. The whole complex - see synonyms - is in need of revision.
