Genera of phytopathogenic fungi known from culture: 1–379.

Approximately 200000 species of fungi have been described to date, representing nearly 8000 currently recognised genera. Many of these genera are regarded as plant pathogenic, as they include at least one species proven to cause pre- or postharvest plant disease. Following the abandonment of dual nomenclature and the advent of DNA sequencing and phylogenetic approaches, numerous para- and polyphyletic clades were resolved into distinct genera. These genera are now defined based on morphology, ecology, and DNA phylogeny. The present paper represents the first in a series that aims to provide descriptions, classification, illustrations, significant species, disease symptoms, and DNA data for the common genera of phytopathogenic fungi known from culture, including the first treatment of 379 genera. In addition, several new combinations, lecto-, epi-, or neotypes are also proposed. <b>Taxonomic novelties: New combinations:</b> <i>Anisogramma coryli</i> (Batsch) Crous, <i>Helostroma bacarum</i> (Buhagiar) Aime & Bensch, <i>Hymenella cerealis</i> (Ellis & Everh.)
