Acarospora austriaca H. Magn.
Lichenised. Poorly known taxon.
Substrate: siliceous rocks
Altitudinal distribution: subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: the type, from the Austrian Alps, is perhaps A. helvetica, but according to Roux et coll. (2014) it is different from A. complanata.
