title: Perezia Microsporidia vs. Perezia Viridiplantae: Homonymy under the ICN with comments on jurisdiction of the ICN or ICZN over nomenclature of the Microsporidia and a brief discussion of this microsporidian genus and its species.
abstract: Until recently, the taxon PereziaLéger and Duboscq (1909) (Fungi: Microsporidia) (non-La Gasca, 1811, Viridiplantae: Asteraceae) was a preoccupied name because both it and its senior homonym were regulated under the International Code of Nomenclature of Algae, Fungi, and Plants. This meant that the microsporidian genus name required replacement, as did Pereziidae Loubes [sic], Loubes et al. (1977), as that name was based on a homonymous genus name and therefore illegitimate. However, a recent decision by the ICN to return microsporidians to the auspices of the International Code of Zoological Nomenclature removes this homonymy, but causes a potential problem because current language of the ICZN is not written in a way that allows microsporidians to return to its jurisdiction. Language in the ICZN requires modification in order to avoid microsporidians becoming "code orphans." The species of Perezia Léger and Duboscq are reviewed.
