Substrate: intermediate rocks (such as calciferous schists)
Altitudinal distribution: submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)
Note: a species peculiar in having a rather large, whitish-pruinose thallus with very narrow, deeply incised, convex lobes, and sessile apothecia with brown, non-pruinose discs; on schists with various contents in calcium; so far only known from the Western Alps (France).
