Candelariella coralliza (Nyl.) H. Magn.

A lichen characteristic by its yellow thick areolate thallus. It has a relatively well-defined ecology – it prefers exposed, eutrophicated rocks and boulders. These are usually tops of acidic volcanic or siliceous rocks, eutrophicated by bird excrements. In nutrient-rich localities, the species may be found even out of this specific habitat. The lichen is widespread and relatively common in Europe. In the Czech Republic, it is locally abundant, occurring from lowlands to mountains. Sometimes, it may be hardly distinguished from the common C. vitellina, whose thallus is squamulose or with flat areoles. The ecology and appearance of both species is partly overlapping and some authors consider C. coralliza as an extreme morphotype of C. vitellina.
