Caloplaca epithallina Lynge
Lichenised.
Substrate:
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 rather continental species found on well-lit surfaces of siliceous rocks, e.g. on isolated boulders in grasslands, growing on other crustose and even foliose lichens (common hosts in the Alps are Dimelaena oreina, Psorinia conglomerata, Rhizoplaca spp., Umbilicaria spp.); most frequent in dry-continental valleys of the Alps.
