Rinodina dubyana (Hepp) J. Steiner

Rinodina dubyana has a light-grey to white thallus, which is predominantly endolithic (i.e., immersed in the rock substrate). Its apothecia have a lecideine margin, so it resembles Buellia species (it used to be named Buella dubyana). It has small Dubyana-type spores. The lichen is rather thermophilic, in Europe mainly distributed in the Mediterranean. It occurs on exposed calcareous rocks and stones, e.g., on rocky steppes. In the Czech Republic, R. dubyana was published only once from the Svatý kopeček hill by Mikulov (Suza 1921). Since then, it has not been found in the locality or elsewhere in the Pálava Hills.
