Ionaspis ceracea (Arnold) Hafellner & Türk

Syn.: Aspicilia ceracea Arnold, Hymenelia ceracea (Arnold) M. Choisy, Lecanora ceracea (Arnold) Stizenb.

Lichenised.

Substrate: siliceous rocks

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) 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 siliceous pebbles and stones near the soil; widespread in the Alps, but often overlooked, or confused with small Acarospora-species.
