Typification of Fusarium cerealis and Fusarium crookwellense.
Fusarium cerealis and F. crookwellense are names applied to the same species. The first name, which has nomenclatural priority, is more commonly used, but the second name is still frequently employed. Critical examination of the literature demonstrates that the presumed type of F. cerealis in K is not the holotype and we were unable to locate original material in any other herbarium. The epithet cerealis was used in Fusarium by Wollenweber for a variety of F. culmorum that seems to represent the modern concept of F. cerealis. The International Code of Botanical Nomenclature allows us to designate a neotype for F. cerealis. The only option for maintaining usage of the name F. crookwellense would be to propose its conservation, a strategy that would be unlikely to succeed because of the dominant usage of cerealis. Therefore, the most likely solution is to recommend abandonment of F. crookwellense, and to formalize the synonymy by neotypification of F. cerealis with a conspecific specimen.
