Gyalecta rosea (Schaer.) ined. (provisionally placed here, ICN Art. 36.1b)

Syn.: Lecidea rosea Schaer.
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 with a thin, white, rough thallus and urceolate, immersed apothecia with rose to flesh-coloured discs crowned by a thalline margin; the microscopic characters are unknown and the generic placement is in need of re-evaluation; this could possibly be the oldest name for one of the calcicolous Gyalecta-species; on calcareous rock at high elevation, only known from the type locality in the Western Alps (Switzerland).
Switzerland: Bern;
