Goplana Dioscoreae-Alatae Nom. Nov and Other Uredinales On Dioscoreaceae: Nomenclature and Taxonomy

Abstract

Among the sixteen species of rust fungi described on Dioscoreaceae, three require replacement names. This paper re-describes and proposes Goplana dioscoreae-alatae as a replacement name for Goplana dioscoreae Cummins, nom. illegit. We also propose Uredo dioscoreae-doryphorae as a replacement name for Uredo spinulosa Y. Ono, nom. illegit.; and Aecidium tumbayensis as a replacement name for Aecidium dioscoreae J.C. Lindq., nom. illegit. We discuss nomenclatural controversies surrounding these taxa.
