Protoparmeliopsis bolcana (Pollini) Lumbsch

Syn.: Lecanora bolcana (Pollini) Poelt, Lecanora muralis (Schreb.) Rabenh. subsp. bolcana (Pollini) Clauzade & Cl. Roux, Lecidea bolcana Pollini
Lichenised.
Substrate: siliceous rocks
Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: ecologically similar to P. muralis, but more restricted to natural habitats, on less basic substrata, and with optimum in the Mediterranean belt; apparently more frequent in the Western and Southern Alps.
