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 forming small, chalky-white, rimose thalli and black, sessile apothecia with relatively few subspherical ascospores per ascus; on limestone at low elevations; rare in Europe, but perhaps not recognised or overlooked, with a few records from the Western Alps only (France).
