Fusarium 
/fjuˈzɛəriəm/ is a large genus of filamentous fungi, part of a group often referred to as hyphomycetes, widely distributed in soil and associated with plants. Most species are harmless saprobes, and are relatively abundant members of the soil microbial community. Some species produce mycotoxins in cereal crops that can affect human and animal health if they enter the food chain. The main toxins produced by these Fusarium species are fumonisins and trichothecenes.
The name of Fusarium comes from Latin fusus, meaning a spindle.
The taxonomy of the genus is complex. A number of different schemes have been used, and up to 1,000 species have been identified at times, with approaches varying between wide and narrow concepts of speciation ('lumpers' and 'splitters').
Phylogenetic studies indicate seven major clades within the genus.
Various schemes have subdivided the genus into subgenera and sections. There is a poor correlation between sections and phylogenetic clades.
