Dermatocarpon rivulorum (Arnold) Dalla Torre & Sarnth.

Syn.: Endocarpon rivulorum Arnold

Lichenised.

Substrate: siliceous rocks,

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a widespread, cool-temperate to arctic-alpine, circumpolar species found on periodically submerged siliceous rocks, in seepage tracks or along small streams, often completely inundated during summer, also occurring in melt-water seepages below snow-beds and along lakeshores.
