Peltigera extenuata (Nyl. ex Vain.) Lojka

Syn.: Peltigera canina (L.) Willd. var. extenuata Nyl. ex Vain., Peltigera didactyla (With.) J.R. Laundon var. extenuata (Nyl. ex Vain.) Goffinet & Hastings

Lichenised.

Substrate: living mosses, siliceous rocks,

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: this species has more or less the same ecology as P. didactyla, but seems to be most frequent in the montane belt, and differs in the richly branched rhizines and the C+ red medulla.
