LICHALP

Lambiella furvella (Nyl. ex Mudd) M. Westb. & Resl

Syn.: Lecidea furvella Nyl. ex Mudd, Lecidea furvula Nyl., Lecidea orphnaeilla Stirt., Lecidea spongiosula Nyl., Rimularia furvella (Nyl. ex Mudd) Hertel & Rambold

Lichenised.

Substrate:

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 species with a brown, rimose to areolate thallus, the areoles with minute granular isidia easily and soon breaking down to form confluent sorediate crusts, usually sterile; sometimes confused with Miriquidica intrudens, but lacking the paler margin of the areoles and the black marginal soralia; on exposed siliceous rocks, where it acts as a non-specialised parasitic lichen (frequent hosts are species of Rhizocarpon, Aspicilia, Lecidea, Lecanora and others); widespread in the Northern Hemisphere; widespread in the Alps, but probably overlooked in some regions.
