Remarks (internal):Type material of this species is not preserved. The selected neotype represents original material from de Thümen's herbarium. Vimba's (1970) description of R. primulae comprises R. primulae s.str. as well as R. interstitialis. The two species are, however, easily separable and quite different from each other. The latter species possesses consistently aseptate conidia. The conidia in R. primulae are catenate and the conidial shape and width are quite distinct.
