Lecidea pseudoplana Hertel ined.

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 silicicoloous species resembling L. paratropoides, but with a different chemistry (planaic acid); in the study area so far only known from the Eastern Alps (Austria).
