Lichenised.

Substrate:

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)

Note: a mainly warm-temperate species found on compact limestone, more rarely dolomite, in sheltered situations, with optimum in open woodlands, growing on the thalli of Bagliettoa-species with an involucrellum, especially B. parmigera and B. parmigerella. The species is morphologically variable but, pending further study, it is still treated here in a very broad sense (for a different arrangement see Roux et coll. 2014). In the past, it might have been confused with C. oasis.
