LICHALP

Collema glebulentum (Nyl. ex Cromb.) Degel.

Syn.: Collema coralliferum Degel., Collema furvellum Räsänen, Leptogium glebulentum Nyl. ex Cromb.

Lichenised.

Substrate: siliceous rocks, acidic soil (mostly on siliceous substrata)

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 basic siliceous rocks in humid situations; perhaps somehow more widespread throughout the Alps, but often confused with other species.
