Enchylium coccophorum (Tuck.) Otálora, P.M. Jørg. & Wedin

Syn.: Collema coccophorum Tuck., Collema crenatum (Müll. Arg.) Zahlbr., Collema harmandii Samp.
Lichenised.
Substrate: calciferous rocks
Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: on calciferous soil in dry grasslands; this almost cosmopolitan species of dry areas - which can be easily mistaken for E. tenax - might be more widespread in the Alps.
