Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: a species similar to the calcicolous L. sylvestris, with a thin, continuous to rimose-areolate thallus coloured in shades of grey, sessile apothecia which are convex from the beginning, with brown discs and soon excluded margins; on siliceous rocks and boulders, often in shaded habitats near the coast; widespread in Western Europe; the only record from the Alps needs confirmation.
