LICHALP

Lecidea paupercula Th. Fr.

Syn.: Lecidea atroocarpoides Vain., Lecidea kittilensis Vain.

Lichenised. Poorly known taxon.

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 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 close to L. praenubila, not generally accepted as distinct, characterised by the thin areoles with a red-brown centre and paler margin and the dark brown hypothecium, based on a type from Northern Norway; on siliceous rocks at high elevations; the identity of Alpine records is uncertain.
