LICHALP

Stereocaulon vesuvianum Pers. var. vesuvianum

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: on (mostly) acid volcanic rocks; several records from the Alps need re-confirmation.
