LICHALP

Caloplaca bryochrysion Poelt

Syn.: Calogaya bryochrysion (Poelt) Vondrák

Lichenised.

Substrate: , living mosses, 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: on mosses, soil and plant debris over calcareous substrata, but also directly on calcareous rocks, in sheltered but light-rich situations, with optimum above treeline; very much overlooked, or confused with other sorediate species in the Alps; the relationships with C. epiphyta await clarification.
