Lichenised.

Substrate: calciferous rocks

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)

Note: a species of the C. xerica-group with a grey, but often whitish-pruinose, areolate thallus, the areolae with marginal soralia, apothecia (if present) with orange to brown disc, a zeorine exciple with an orange parathecium and a grey thalline margin, ascospores ellipsoid, with septal thickening c. 1/3 to 1/2 as long as the total length; on concrete, mortar or siliceous pebbles in manured places; hitherto mainly reported from Eastern Europe but probably more widespread, at least in the continental inner Alpine valleys.
