Biatora valerii Anzi

Syn.: Lecidea valerii (Anzi) Jatta
Lichenised. Poorly known taxon.
Substrate: siliceous rocks
Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)
Note: a species with a pinkish white, orbicular, thick, almost pulvinate, plicate thallus, the individual thalli solitary to confluent, 5-8 mm across, 2-4 mm tall, apothecia and spores as in Lecanora polytropa; only known from the type collection, on schist, this taxon would be well worthy of further study.
