Clauzadeana macula (Taylor) Coppins & Rambold

Syn.: Aspicilia morioides Blomb. ex Arnold, Clauzadeana instratula (Nyl.) Cl. Roux, Lecanora morioides (Blomb. ex Arnold) Blomb., Lecidea instratula Nyl., Lecidea macula Taylor, Lecidea perustula Nyl., Lecidea pissodes Stirt., Psora pissodes (Stirt.) Walt. Watson

Lichenised.

Substrate: siliceous rocks,

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) 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 hard, steeply inclined crystalline siliceous rocks; probably overlooked in the Alps, but certainly not common.
