Gyalolechia subbracteata (Nyl.) Søchting, Frödén & Arup

Syn.: Caloplaca subbracteata (Nyl.) Lettau, Fulgensia fulgens (Sw.) Elenkin f. subbracteata (Nyl.) Nimis, Fulgensia sorediosa Klem., Fulgensia subbracteata (Nyl.) Poelt, Lecanora subbracteata Nyl.

Lichenised. Poorly known taxon.

Substrate: calciferous soil

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 ground, in clearings of grasslands and shrublands, with optimum in the Mediterranean belt. A critical taxon, characterised by schizidia, which, however, also occur in other related species. According to Roux et coll. (2014), it cannot be separated from G. fulgens, the schizidia being just a re-generation form from damages to the thallus, but molecular data show that the two taxa are distinct (see Nimis 2016).
