Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: closely related to (or identical with) C. obscurella, this name is applied to richly fruiting populations with endophloeodic to thin scurfy thallus lacking the crateriform soralia diagnostic for C. obscurella; based on a type from Croatia; on eutrophic bark of e.g. roadside trees at low elevations; distribution poorly documented because often not distinguished from C. obscurella.
