Validation of five Peronospora species names

Abstract

Some Peronospora names included in the last major taxonomic treatment (a 1991 annotated list of names) were invalid because the author failed to provide the Latin description required at the time of their proposal. Here five such names—Peronospora coronillae-minimae, P . erini, P. papaveris-pilosi, P. ranunculi-flabellati, and P. viciicola—are validated either by providing an English description or by reference to the original English description.
