Lichenised. Poorly known taxon.

Substrate: ,

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: a widespread, perhaps non-lichenised species, often growing on Acarospora. The species is heterogeneous and in need of revision.
