Syn.: Aspicilia excavata G. Thor & Timdal, Aspicilia moenium (Vain.) G. Thor & Timdal, Endocarpon moenium Vain.
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 mainly temperate, inconspicuous species, usually sterile, the rare case of a sorediate Acarospora; certainly more widespread on man-made substrata (mortar, cement, etc.), or more rarely on calciferous schists, on steeply inclined faces.
