LICHALP

Acarospora hellbomii H. Magn.

Syn.: ?Acarospora marcii H. Magn.

Lichenised. Poorly known taxon.

Substrate: siliceous rocks, metal-rich siliceous rocks

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: the type, from extra-Alpine Europe (Scandinavia), is perhaps identical with A. peliscypha; the synonymy with A. marcii, which is also based on a type from extra-Alpine Europe (SW Europe), is uncertain.
