LICHALP

Gyalecta russula (Körb. ex Nyl.) Baloch, Lumbsch & Wedin

Syn.: Belonia fennica Vain., Belonia russula Körb. ex Nyl., Beloniella cinerea Norman, Gyalecta bacidiospora (Eitner) Zahlbr., Secoliga bacidiospora Eitner

Lichenised.

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

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, probably circumpolar species found on base-rich soil, often on bryophytes, and on steeply inclined or underhanging surfaces of basic siliceous rocks, with optimum above treeline; perhaps more widespread in the Alps, but generally not common.
