Aspicilia proluta (Nyl.) Hue

Syn.: Aspicilia submersa (Lamy) Hue, Lecanora caesiocinerea Nyl. ex Malbr. f. proluta Nyl., Lecanora proluta (Nyl.) Zahlbr., Lecanora subdepressa (Arnold) Nyl. var. submersa Lamy, Lecanora submersa (Lamy) Zahlbr.

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: the differences from A. aquatica (both species have ascospores of comparable size) are in need of re-evaluation; on periodically or constantly inundated siliceous rocks; a poorly known taxon based on a type from the Pyrenees, whose distribution is insufficiently known.
