Syn.: Haematomma coccineum (Dicks.) Körb. var. porphyrium (Pers.) Th. Fr, Haematomma porphyrium (Pers.) Zopf, Lichen haematomma Ehrh. var. porphyrius Pers.

Lichenised.

Substrate: siliceous rocks

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: a mild-temperate taxon, much rarer on bark than the typical variety, and perhaps slightly less photophytic.
