Altitudinal distribution:

Note: a species with an endolithic to verrucose, usually rimose thallus and black, sessile, lecideoid apothecia with a persistent thin margin and a dark hypothecium, asci of Byssoloma-type, and small, narrowly ellipsoid ascospores; on siliceous pebbles in open habitats (ecologically similar to Porpidia crustulata); widespread in the Holarctic region but also recorded from the Southern Hemisphere, with a few records from the Eastern Alps (Austria), but distribution in the Alps likely to be incompletely documented.
