LICHALP

Caloplaca anularis Clauzade & Poelt

Syn.: Caloplaca scrobiculata auct. non. H. Magn.

Lichenised.

Substrate: calciferous 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 of the Eurasiatic mountains, from the temperate zone southwards, found on steeply inclined, compact limestone and dolomite; perhaps more frequent but undercollected in the Alps because of its preference for sites which are of difficult access.
