Syn.: Lecanora subdeflexa Nyl.
Lichenised.
Substrate: bark
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 mild-temperate, perhaps holarctic lichen found on isolated trees, especially Fraxinus, Populus and Juglans, often near the base of the trunks; widespread in the Alps, but not common, and probably declining.
