Opegrapha dolomitica (Arnold) Clauzade & Cl. Roux ex Torrente & Egea subsp. omninocalcicola Cl. Roux

Lichenised. Poorly known taxon.
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 taxon characterised by scarcely umbonate, never gyrose ascomata, whose taxonomic value is in need of evaluation; on compact calcareous rocks, with an ecology resembling that of Naetrocymbe saxicola; so far only known from the Western Alps at low elevations, but not consistently distinguished elsewhere in the Alps.
