LICHALP

Aspicilia nunatakkorum (Poelt) Poelt ex Hafellner & Türk

Syn.: Aspicilia mastrucata (Wahlenb.) Th. Fr. f. pseudoradiata Arnold, Lecanora nunatakkorum Poelt

Lichenised.

Substrate: siliceous rocks

Altitudinal range: from the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers) to the nival belt (above the lower limit of perennial snow and glaciers)

Note: a species with a (non-effigurate!) dark-grey, papillate (to almost dwarf-fruticose) thallus partially reacting K+ red, often sterile, but sometimes with solitary, sessile apothecia; on exposed siliceous rocks at high altitudes; the distribution is still insufficiently known, but is probably wider than the few records would suggest.
