Abstract
We are currently in the middle of a revolution in fungal taxonomy. Taxonomy is at the crossroads, where phenotypic data must be merged with DNA and other data to facilitate accurate identifications. These data, linked to open access journals and databases, will facilitate the stability of nomenclature in the future. To achieve this, however, plant pathologists must embrace new technologies, and implement these policies in their research programmes.
