Using the correct name for phytopathogenic fungi and oomycetes is crucial for communicating knowledge and simplifying the process of finding the correct name, with DNA technologies playing a key role in connecting different morphs of the same species. The move towards a more natural classification system and the introduction of molecular systematics are driving forces for the reclassification of fungi, including pathogens. This article outlines steps to aid in determining the correct name and provides a list of accurate names for common genera and species of phytopathogenic fungi.
Using the correct name fur phytupathugenic fungi and uumycetes is essential for communicating knowledge about species and their biology, control, and quarantine as well as for trade and research purposes. However, many plant pathogenic fungi are pleomorphic, meaning they produce different asexual (anamorph) and sexual (teleomorph) morphs in their life cycles. Therefore, more than one name has been applied to different morphs of the same species, which has confused users. The onset of DNA technologies makes it possible to connect different morphs of the same species, resulting in a move to a more natural classification system for fungi in which a single name for a genus and species can now be used. This move to a single nomenclature. coupled with the advent of molecular systematics and the introduction of polythetic taxonomic approaches. has been the main driving force for a reclassification of fungi. including pathogens. Nonetheless, finding the correct name for species remains challenging. In this article we outline a series of steps or considerations to greatly simplify this process and provide links to various online databases and resources to aid in determining the correct name. Additionally, a list of accurate names is provided for the most common genera and species of phytopathogenic fungi.
