LICHALP

Buellia arnoldii Servít

Syn.: Hafellia arnoldii (Servít) Hafellner & Türk

Lichenised.

Substrate: bark

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 mild-temperate species found on thin twigs of conifers in humid stands, with optimum in the subalpine belt; probably overlooked and more widespread in the Alps.
