Phaeophyscia chloantha (Ach.) Moberg

A lichen similar to, e.g., P. endophoenicea and P. orbicularis, distinguished by characteristic soralia and pale thallus underside. From all the Czech Phaeophyscia species, it is microscopically distinguished by prosoplectenchy­matic cortex. Due to this character it is sometimes placed in a separate genus Physciella. The lichen typically grows on more nutrient-rich bark of deciduous trees in open forests, parks or orchards. More rarely, it can be found on calcareous shaded mossy rocks. It is probably sensitive to eutrophication and substrate acidification. In Europe, P. chloantha is abundant in warmer regions and is considered a sub-Mediterranean species. In the Czech Republic, it has recently been recorded mainly in central Bohemia and southern Moravia. The species was described from the Czech Republic as Physcia pragensis by Josef Nádvorník (Nádvorník 1947). A specimen collected near Ostrožská Lhota village in the Uherské Hradiště region was selected as lectotype. Today it is considered a synonym of P. chloantha.
