Poeltinula cerebrina (DC.) Hafellner subsp. parvocalcicola Cl. Roux

Syn.: Encephalographa cerebrina (DC.) A. Massal. subsp. parvocalcicola Asta & Cl. Roux [invalidly published, ICN Art. 40.1 + 8], Poeltinula cerebrina (DC.) Hafellner subsp. parvocalcicola (Asta & Cl. Roux) Clauzade & Cl. Roux comb. inval.

Lichenised.

Substrate: calciferous rocks, intermediate rocks (such as calciferous schists)

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: a taxon differing from the nominal subspecies in the more exposed apothecial discs and the greenish epihymenium; on calcareous schists, ecologically similar to Stenhammarella turgida; only known from the Alps, rarely recorded, but probably not consistently distinguished.
