LICHALP

Miriquidica deusta (Stenh.) Hertel & Rambold

Syn.: Lecanora deusta (Stenh.) Nyl., Lecidea deusta (Stenh.) Nyl., Lecidea deustata Zahlbr., Lecidea fuscoatra (L.) Ach. var. deusta Stenh., ?Lecidea secernens H. Magn.

Lichenised.

Substrate: siliceous rocks

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) 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 much misunderstood and overlooked species (being mostly sterile), with a probably western and southern distribution in Europe, found on exposed surfaces of base-rich siliceous rocks, with a wide altitudinal range. Records from Austria are in need of critical revision.
