Calicium corynellum (Ach.) Ach.

A saxicolous species resembling a more common C. viride from which it differs by shorter stalks of fruiting bodies, whitish pruina on the exciple, leprose thallus and also chemically (Tibell 1999). It grows on overhanging siliceous rocks in humid, shady habitats. In Europe this lichen is rare, distributed mainly across boreal and colder temperate areas. There are only historical reports on its occurrence from several regions of the Czech Republic. The last report, verified by Vězda (1998), is from an unspecified locality in the Třebíč region. In fact, most of all the historical records come from this area.
