LICHALP

Umbilicaria proboscidea (L.) Schrad.

Syn.: Gyrophora polymorpha Schrad. var. proboscidea (L.) Schaer., Gyrophora proboscidea (L.) Ach., Lichen proboscideus L.

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 mainly arctic-alpine, circumpolar lichen found on siliceous rocks, often on small boulders, ecologically similar to U. cylindrica, but with a narrower range, with optimum in colder and less continental areas, mostly above treeline.
