Hypogymnia vittata (Ach.) Parrique

A circumboreal mountain species, rare in the Czech Republic. It resebles H. physodes, but differs in subtle morphological characteristics, such as the more prolonged, overhanging lobes with black underside, side lobes, and a negative reaction with K and Pd. The lichen is most often found on mossy tree trunks in well-preserved mountain forests, less often also on mossy siliceous rocks. In the Czech Republic, it has been recently reported only from the Šumava Mts (several localities), the Novohradské hory Mts (Žofínský prales) and the Hrubý Jeseník Mts (Praděd, Šerák-Keprník). In the past, H. vittata used to occur also in other mountain localities and less often even at lower elevations, where it has disappeared in consequence of acid rain, intensification of agriculture and forestry.
