Rinodina capensis forms white to pale grey crusts and apothecia with a conspicuous pale grey margin. Its spore cell wall has a characteristic thickening (Physcia type) and contains atranorin in the thallus. R. exigua is similar, but has smaller spores, less conspicuous thallus and different anatomy of apothecia.
It grows on subneutral bark of deciduous trees (beech, maple, ash) and prefers well-lit sites such as scree forests or solitary trees. In the Czech Republic, the lichen is distributed mainly in the mountains. It is more abundant in the Šumava Mts and known also from the Beskydy Mts. It has also been recorded at lower elevations of the flood-plain forest reserve Ranšpurk in southern Moravia.taxonomic classification:
