Peltigera collina (Ach.) Schrad.

A relatively well-identifiable epiphytic Peltigera with sorediate lobe margins. The species may be mistaken only for the ecologically similar Nephroma parile. Peltigera collina is a typical rare macrolichen of moist old-growth forests, where it occurs for example together with Lobaria pulmonaria. It prefers mossy trunks of old beeches and sycamores in mountain areas rich in precipitation. Besides, it may be found also on mossy rocks and boulders. The lichen is very sensitive to air pollution, eutrophication and changes in microclimatic conditions, for example, due to intensive forest management. In central Europe, P. collina is currently rare. In the Czech Republic, there is a number of historical records mainly from mountain areas in the Šumava and Hrubý Jeseník Mts. Currently, the species is very rare in the country, restricted to only a few trees near Modrava in the Šumava Mts.
