Lecanora biformis (Ramond) Clauzade & Cl. Roux
Syn.: Lecidea biformis (Ramond) Ramond, Lichen biformis Ramond
Lichenised.
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 recalling L. sulphurea, but with a thinner thallus and smaller, aspicilioid apothecia; on siliceous rocks in upland areas; in the study area so far known from a few localities in the Western Alps (France), but perhaps not recognised elsewhere.
