C, Conidiogenous cells. D, Conidia. at Blainville in 1906 labelled 'Phyllosticta cytospora mini' present which agrees in all details with Vouaux's original description and later collections; the Blainville specimen is consequently designated as neotype for this name here. The name Phyllosticta lichenicola Allescher may have been partly based on a fungus very close to Phoma cytospora (see p. 83). Phoma caperatae
