Syn.: Lichen leptophyllus Ach.
Lichenised.
Substrate: calciferous 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 of the D. miniatum-group with umbilicate thalli usually provided with blackish grey, concave lobes, and subglobose, uniseriate ascospores in cylindrical asci, found on horizontal or depressed rock faces of calcareous rocks in seasonally wet places; from the Alps there are only a few scattered records, but the species might have been not always distinguished from D. miniatum.
