LICHALP

Usnea cavernosa Tuck.

Syn.: Usnea arnoldiana Zahlbr., Usnea lacunosa Willd., Usnea microcarpa Arnold

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: this species seems to be more frequent in Central and Southern Europe; it is restricted to damp montane to subalpine forests, on branches of coniferous and deciduous trees; widespread throughout the Alps.
