Lichenised. Poorly known taxon.
Substrate: calciferous rocks
Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: a species related to P. ardesiaca, with a thin whitish thallus and semi-immersed perithecia with a pigmented wall and an apical involucrellum, but the ovoid ascospores smaller, usually with 3 transversal septa and occasionally a single, incomplete longitudinal septum; on limestone in Central Europe and in the mountains of the Mediterranean region; apparently rare in the Alps, being only known from Austria.
