Bryoria bicolor (Ehrh.) Brodo & D. Hawksw.

A sensitive, critically endangered Bryoria species, characteristic by its conspicuous two-coloured thallus. It grows on mossy rocks and trees (mainly spruces) in well-preserved forests of areas rich in precipitation. In the past, it used to occur scattered across the Czech mountains and infrequently also in lower inverse elevations. However, consequent on acid rain, it has noticeably declined latterly. Recently, it has been found only in the Šumava and Hrubý Jeseník Mts, even though, in the 1950s it used to be collected also in the Jizerské hory Mts. Its range covers suboceanic areas of the whole Northern Hemisphere and South America.
