Lecidoma demissum (Rutstr.) Gotth. Schneid. & Hertel

An arctic-alpine terricolous species, occurring on bare soil, often rocky and poorly covered by vegetation, usually in areas with a long-lasting snow cover. A number of brown biatorine apothecia is formed on a conspicuous thallus. In the Czech Republic, the lichen was historically reported from the subalpine zone of the Krkonoše Mts and from the naturally forestless areas in the Hrubý Jeseník Mts, Králický Sněžník Mts and Šumava Mts. It is still relatively frequently seen in suitable habitats in the upper parts of the Krkonoše Mts. Interestingly, the species has been recently found at lower and middle elevations of the Krušné hory Mts, Slavkovský les Mts and Šumava Mts, and in places affected by human activity (such as stone walls, heaps, quarries).
