Rinodina confragosa has a grey thallus containing atranorin and Physcia-type spores. It has characteristic ecology; occurring on vertical and overhanging siliceous rocks, commonly slightly enriched with minerals, accompanied by ombrophobic lichens (e.g., Caloplaca demissa or Lecanora swartzii). It is usually found at exposed or half-shaded places at middle to high elevations. In the Czech Republic, the species used to be recorded repeatedly (see the catalogue by Vězda & Liška 1999). Currently, it is only known from a couple of montane localities: calcareous phyllites at Petrovy kameny in the Hrubý Jeseník Mts, serpentinites in the Křížky nature reserve in the Slavkovský les Highlands, granulite rocks on Kleť Mt in the Blanský les Mts and Peperek in the Žďárské vrchy Highlands.
