Evernia prunastri (L.) Ach.

Evernia prunastri, also known as oak moss, is characterised by the dichotomously branching, yellow-green, sorediate thallus, and by white branch lower side. In the Czech Republic, it is an abundant epiphyte with a relatively wide ecological amplitude. It occurs from lowlands to mountains, growing on illuminated trunks and branches of mainly deciduous trees and shrubs (less often on conifers), and even on wood. Its range is extensive, covers large areas of Eurasia and North America, and extends into North Africa.
