Similar species: A northern species, Coccotylus truncatus (Pallas) Wynne et Heine (formerly Phyllophora truncata) is frequent in Scotland, and in the north of England and Wales to Durham and Anglesey, and in Ireland south to Clare Island. This species is easily distinguished by its gradually expanding stipe.
