Lecanora leucoderma (Anzi) Stizenb.

Syn.: Zeora leucoderma Anzi
Lichenised. Poorly known taxon.
Substrate: calciferous rocks
Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: a species with a thin, white, smooth, cartilaginous thallus, adnate to sessile, small, apothecia with a reddish disc and a very thin margin separated from the disc, and small, ovoid, hyaline, simple ascospores; the type material, collected on shaded calcareous rocks in the Rhaetic Alps (Italy), at 1,900 m, is badly preserved (see Nimis 2016). The species might even belong to Protoblastenia.
