Candelariella vitellina (Hoffm.) Müll. Arg.

One of the most common yellow lichens in the Czech Republic. It has a squamulose to areolate thallus that is usually richly fertile. Individuals with less developed thalli may be mistaken for the calciphilous C. aurella. Candelariella vitellina has a relatively wide ecological amplitude. The species is frequent on various siliceous and volcanic rocks. Beside the natural outcrops, it commonly occurs also in anthropogenic habitats (such as roofs or walls). Rarely, the lichen may be found also on worked timber or on tree bases, especially in dusty places. The species distribution is nearly cosmopolitan. It belongs to common lichens, distributed from lowlands to mountains both in Europe and in the Czech Republic.
