Parmotrema stuppeum (Taylor) Hale

Syn.: Parmelia claudelii (Harm.) Vain., Parmelia maxima Hue, Parmelia stuppea Taylor, Parmelia trichotera Hue var. claudelii (Harm.) Du Rietz

Lichenised.

Substrate: bark, living mosses

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)

Note: a mainly mild-temperate species found in open woodlands with frequent fog, mostly on ancient trees, but also on epilithic bryophytes; rather rare, and certainly declining in the Alps.
