Rinodina interpolata (Stirt.) Sheard

Rinodina with a conspicuous circular grey thallus surrounded by a grey prothallus, resembling the thallus of Caloplaca viridirufa. Apothecia have a proper margin and Physconia-type spores (cell wall thickened around the central septum). The species grows on vertical to overhanging siliceous rocks and tolerates shading. It requires wet microclimate, so it is mainly found on coastal rocks in northern and western Europe. In microclimatically suitable stands, R. interpolata is also found inland. Its only record in the Czech Republic, in the Černé jezero glaciar cirque in the Šumava Mts (Palice 1999), is its most distant known occurrence from the seacoast in Europe.
