LICHALP

Lecidea spuriiformis Anzi

Lichenised. Poorly known taxon.

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 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 with a well-developed, rimose-areolate, white thallus delimited by a black prothallus, small, black apothecia with a prominent proper margin, and elliptical, subacute ascospores measuring c. 18 × 8-10 µm; the type, which well deserves further study, was collected on mica-schists on Mt. Spluga, in Swiss territory.
