Nephroma resupinatum (L.) Ach.

This lichen can be identified by the smoothly tomentose thallus, especially on its margins, and by the white wart-like protuberances on the underside of the thallus. Its typical habitats are moss-covered deciduous trees in old-growth forests and moss-covered boulders or rocks. Nephroma resupinatum is widespread throughout the northern hemisphere. In central Europe, however, this species is rather rare, being restricted to wooded mountain areas. All of its few recent Czech localities are in the Šumava Mts. In the past, it had been reported also from other mountain ranges in the Czech Republic, from where it largely disappeared in the 19th century. Like other members of the Lobarion association, the lichen is very sensitive to microclimatic changes in forest stands and to air pollution.
