LICHALP

Stereocaulon grande (H. Magn.) H. Magn.

Syn.: Stereocaulon paschale (L.) Hoffm. var. grande H. Magn.

Lichenised.

Substrate: acidic soil (mostly on siliceous substrata)

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: a species of alluvial soils with characters intermediate between S. paschale and S. alpinum: podetia crenate-squamulose to digitate-squamulose (larger than in S. paschale, more delicate and divided than in S. alpinum), secondary chemistry with atranorin and lobaric acid; widespread in Europe from the boreal-montane to the subarctic-subalpine zone, but not common; from the Alps there are only some scattered records, but perhaps the species was not always distinguished.
