LICHALP

Lecidea fuscoatrata Nyl.

Syn.: Psora subfumosa (Arnold) Arnold var. fuscoatrata (Nyl.) Arnold

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 taxon resembling L. fuscoatra, but thallus C- and ascospores less than 10 µm long, probably belonging to the L. atrobrunnea-group and close to or even identical with L. subfumosa; on siliceous rocks in the alpine belt; the distribution is insufficiently known.
