a genus of fungi; some species are plant pathogens and some are opportunistic infectious agents of humans and other animals.
A genus of rapidly growing fungi producing characteristic sickle-shaped, multiseptate macroconidia that can be mistaken for those produced by some dermatophytes. Usually saprobic, a few species such as Fusarium oxysporum, Fusarium solani, and Fusarium moniliforme can produce corneal ulcers; some species may cause disseminated infection.

n. pl. fusar·ia (-ē-ə)
Any of various pathogenic fungi of the genus Fusarium, chiefly inhabiting temperate climates and infecting both plants and animals. In humans, infection may cause inflammation of the cornea and external ear.

[L. fusus, spindle]
a genus of fungi; some species are plant pathogens and some are opportunistic infectious agents of humans and animals. Many also produce trichothecene toxins which cause poisoning of animals if the infected material, usually stored feed, is eaten.

causes diarrhea, staggers and food rejection in cattle.
Fusarium solani, Fusarium javanicum
1. growing on sweet potatoes this fungus produces bovine atypical interstitial pneumonia.
2. as an environmental fungus causing melanized granulomas (black gill disease) in shrimps, especially Penaeus japonicus.
