Lichenised. Poorly known taxon.

Substrate: calciferous rocks, siliceous rocks

Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) 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 basic siliceous or slightly calciferous rocks in humid-sheltered situations near or above treeline. A poorly known species of the P. nigrum-complex, which badly needs revision.
