Umbilicaria leiocarpa DC.

Syn.: Agyrophora leiocarpa (DC.) Gyeln., Agyrophora lyngei (Schol.) Llano, Gyrophora leiocarpa (DC.) Du Rietz, Umbilicaria atropruinosa Schaer., Umbilicaria lyngei Schol.

Lichenised.

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 nival belt (above the lower limit of perennial snow and glaciers)

Note: a mainly arctic-alpine, probably circumpolar lichen found on vertical, wind- and sun-exposed surfaces of large siliceous boulders wetted by rain with a short snow cover period, with optimum above treeline.
