Physcia adscendens (Fr.) H. Olivier

Currently, one of the most abundant lichens in the Czech Republic. It often grows together with a similar P. tenella, which has different soralia (so called lip-shaped). It typically occurs within nitrophilous lichen communities together with Xanthoria parietina. It is heliophilic, prefers sun-exposed stands in open landscape and also tolerates intensive agriculture. In forests, P. adscendens usually grows high in tree tops. It may also occur on rock substrates, such as walls, roofs or eutrophicated rocks and stones. The species is common and widely distributed all over Europe. In the Czech Republic, it is very abundant from lowlands to mountains.
