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 species with a finely granulose thallus (as in C. efflorescens), but with 8-spored asci, based on a type from Australia (identity of European samples therefore in need of verification); sterile specimens are usually named C. efflorescens.
