Cetraria obtusata (Schaer.) van den Boom & Sipman
Syn.: Cetraria aculeata (Schreb.) Fr. var. obtusata Schaer.
Lichenised.
Substrate: acidic soil (mostly on siliceous substrata)
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: ecologically similar to C. ericetorum, but much rarer, and perhaps more bound to dry-continental situations.
