Scytinium turgidum (Ach.) Otálora, P.M. Jørg. & Wedin

Syn.: Collema turgidum Ach., Collemodium turgidum (Ach.) Nyl., Leptogium turgidum (Ach.) Cromb.
Lichenised. Poorly known taxon.
Substrate: calciferous rocks
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: on surfaces of calcareous rocks with some water seepage after rain; apparently most frequent in the Southern and Western Alps. This species could prove to be just a growth form of S. schraderi, one where the fruticose part is poorly developed.
