Thelidium inundatum Zschacke
Lichenised.
Substrate:
Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)
Note: an endolithic amphibious lichen found in periodically submerged situations, mostly on calcareous substrata in upland areas, but usually below the alpine belt; from the Alps there are only a few scattered records.
