A conspicuous Rinodina forming grey-brown circular thalli on a smooth tree bark. It has crowded lecanorine apothecia with a thallus margin and minute Milvina type spores (with irregularly and strongly thickened cell wall).
The species typically grows on branches in canopies, but also on smooth bark of young deciduous trees (e.g., beech, ash or rowan). In Europe, it is abundant in the Mediterranean (mainly in montane areas), but distributed also further north, e.g., in Scandinavia. In central Europe, R. sophodes is quite rare because it avoids areas with a continental climate. In the Czech Republic, it has several localities at lower elevations (steppes in Bílé Karpaty and Pálava) and also in the mountains (the Orlické hory and Beskydy Mts).
