In 2021 it was discovered that Fusarium xyrophilum was able to hijack a South American species of yellow-eyed Xyris grass, creating fake flowers, fooling bees and other pollinating insects into visiting them, taking fungal spores to other plants. In humans
Some species may cause a range of opportunistic infections in humans. In humans with normal immune systems, fusarial infections may occur in the nails (onychomycosis) and in the cornea (keratomycosis or mycotic keratitis). In humans whose immune systems are weakened in a particular way, (neutropenia, i.e., very low neutrophils count), aggressive fusarial infections penetrating the entire body and bloodstream (disseminated infections) may be caused by members of the Fusarium solani complex, Fusarium oxysporum, Fusarium verticillioides, Fusarium proliferatum and, rarely, other fusarial species. Research
The isolation medium for Fusaria is usually peptone PCNB agar (peptone pentachloronitrobenzene agar, PPA). : 7  For F. oxysporum specifically, Komadas medium is most common. : 7  Differential identification is difficult in some strains. Vegetative compatibility group analysis is best for some, is one usable method for others, and requires such a large number of assays that it is too complicated for yet others. Use as human food
Fusarium venenatum is produced industrially for use as a human food by Marlow Foods, Ltd., and is marketed under the name Quorn in Europe and North America. Also, Fusarium str. yellowstonensis is under investigation for similar foods.Some consumers of fusarium products have shown food allergies similar in nature to peanut and other food allergies. People with known sensitivities to molds should exercise caution when consuming such products.
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. Despite most species apparently being harmless (some existing on the skin as commensal members of the skin flora), some Fusarium species and subspecific groups are among the most important fungal pathogens of plants and animals. The name of Fusarium comes from Latin fusus, meaning a spindle. Taxonomy
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.There is a proposed concept – widely subscribed by specialists – that would include essentially the genus as it now stands, including especially all agriculturally significant Fusaria. There is a counterproposal (unrelated to Watanabe 2011) that goes far in the other direction, with seven entirely new genera. Subdivision
Various schemes have subdivided the genus into subgenera and sections. There is a poor correlation between sections and phylogenetic clades.Sections previously described include:
