Caloplaca ammiospila (Wahlenb.) H. Olivier

A species with a grey thallus and red apothecia, currently included in the genus Blastenia. Its usual substrate are bryophytes on base-rich or calcareous soils and rocks in alpine locations. It is a relatively common lichen of European and Asian mountains. However, in the Czech Republic, the only reliable evidence is the occurrence on Petrovy kameny in the Hrubý Jeseník Mts, where the species has repeatedly been collected. It grows there in a small population in crevices of calcareous phyllites.
