Atla alpina Savić & Tibell
Syn.: Polyblastia theleodes auct. p.p.
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: on calcareous rocks (mesozoic limestone, marble of variable ages) with at least locally increased humidity; widespread and fairly common throughout the Alps, but often filed under ""Polyblastia theleodes"", and hence under-recorded.
