Hypogymnia bitteri (Lynge) Ahti

A rare mountain species which resembles the common H. physodes. However, it differs in the conspicuously brown thallus margins and capitate soralia on side lobes. The lichen has a circumpolar distribution in the boreal zone and mountains of the northern hemisphere. It occurs also in South America and east Africa. In central Europe, the species is common, for example, in the Alps. It grows on acidic bark of mainly conifers in mountain spruce and peat forests. It meets its optimum near the upper tree line. Occasionally, the lichen may be found on wood or siliceous rocks. In the Czech Republic, Hypogymnia bitteri is very rare, reported only from the Šumava Mts, Krkonoše Mts, Českomoravská vysočina uplands (historically; Liška & Pišút 1995) and once from blackthorn in the foothills of the Doupovské hory Mts.
