Rinodina orculata Poelt & M. Steiner

Rinodina orculata has a minute grey-brown thallus with numerous lecanorine apothecia producing Physconia type spores (the cell wall thickened mainly around the septum). A similar R. trevisanii has bigger spores. R. orculata occurs on an exposed bark of deciduous and coniferous trees in mountain areas. It can be found as high as in the subalpine belt, where it grows on small shrubs, e.g., Rhododendron (Nimis et al. 2008). In the Czech Republic, the species only occurs on sycamores in the Šumava Mts; in the Plešné jezero glacial cirque and the surroundings of Modrava. Recently, it was found also in the Beskydy Mts.
