Syn.: Haematomma lapponicum Räsänen, Haematomma ventosum (L.) A. Massal. var. lapponicum (Räsänen) Lynge
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 nival belt (above the lower limit of perennial snow and glaciers)
Note: a species with narrowly ellipsoid (not acicular!) ascospores which are simple to 1-septate at maturity; on siliceous rocks in windy situations; widespread and often common in the Arctic, very rarely reported from the orobiomes of the temperate zone, including the Alps; the few Alpine records (France) urgently need verification.
