Bryoria tenuis (E. Dahl) Brodo & D. Hawksw.

Syn.: Alectoria tenuis E. Dahl
Lichenised.
Substrate: bark
Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: a species described from Greenland, with erect to decumbent thalli with blackened bases and at least some perpendicular lateral spines, therefore recalling B. bicolor (but lacking the third-order perpendicular branches of that species); Austrian specimens - despite their mention in one of the major genus monographs - are in urgent need of critical revision.
Austria: Vorarlberg; Tirol; Salzburg; Kärnten;
