The paper by Bodensteiner et al.[ indicates that Rhodocyphella is closely linked to Resupinatus and Stigmatolemma. But the latter genus is already merged with Resupinatus according to Index Fungorum, and it seems likely that Rhodocyphella should also be merged into the same taxon.]
Rhodocyphella is not to be confused with Rhodocybella, which is also a small genus of cyphelloid fungi growing on bark, but which belongs to family Entolomataceae.
