Lobothallia radiosa (Hoffm.) Hafellner

A species characteristic for sunny limestones. However, it may be found on a variety of other rocky substrates rich in calcium, including the anthropogenic ones. The lichen is widespread in Europe, occurring from lowlands to mountains. In the Czech Republic, Lobothallia radiosa is abundant only locally, in areas with basic rocks. In several regions, it is completely absent.
