Ramalina fraxinea (L.) Ach.

Ramalina fraxinea, with its characteristic pendent and fertile thalli, is one of the largest Ramalina species in central Europe. It grows on trunks and bigger branches of older deciduous trees with higher bark pH (mainly on maples) in open landscapes, e.g., trees along roads, parks or solitary trees even in inhabited areas. In Europe, the species is distributed all over the continent, except heavily air-polluted areas or regions with intensive agriculture. In the Czech Republic, it significantly receded during the second half of the 20th century due to acid rain. Currently, R. fraxinea is more abundant in southern and south-western Bohemia (mainly the Šumava Mts), it is rare elsewhere and completely absent from the northern Bohemia. It prefers humid localities, typically in mountains and their foothills.
