LICHALP

Euopsis granatina (Sommerf.) Nyl.

Syn.: Lecanora granatina Sommerf., Pyrenopsis granatina (Sommerf.) Nyl.

Lichenised.

Substrate: siliceous rocks

Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) to the nival belt (above the lower limit of perennial snow and glaciers)

Note: a species with an areolate thallus, the granulose areoles being dark brown and spotted pale brown due to the presence of two photobionts, the minute lecanorine apothecia recalling small garnets; on periodically wet siliceous boulders and outcrops in sunny places; widespread in the Holarctic region but altogether rare, also recorded from Papua New Guinea; for the Alps only reported from two distant localities.
