Peltigera praetextata (Flörke ex Sommerf.) Zopf

One of the most common genus members in the Czech Republic and at the same time the most common forest Peltigera species. Its typical feature are the squamulose isidia, so-called phyllidia, often absent on fertile forms, which may be easily mistaken for other genus members. The species most often occurs on mossy rocks, decaying logs and tree bases in forests. It may be found even in open landscape if the habitat is sufficiently humid. The lichen grows on both acidic and basic substrates from lowlands to mountains. Even at the level of the entire northern hemisphere, it is one of the most common Peltigera species. Surprisingly, despite being so widespread, the lichen is rare in same regions of the Czech Republic. It avoids intensively managed, highly eutrophicated and acidified areas.
