LICHALP

Hertelidea botryosa (Fr.) Printzen & Kantvilas

Syn.: Biatora botryosa Fr., Lecidea botryosa (Fr.) Th. Fr.

Lichenised.

Substrate: bark, lignum

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 probably circumboreal-montane to cool-temperate lichen found on lignum, often on burnt trunks of conifers and Quercus, more rarely on acid bark, usually in upland areas but below treeline; with several scattered records from the Alps.
