Fusarium sp.

Genus/species (aliases): Fusarium sp.

Classification: Ascomycete


  • Cell: Dependent on species
  • Colony: Dependent on species
  • Spore: In F. oxysporum, there are three types of spores: microconidia, macroconidia, and chlamydospores
  • Zygote: Asexual
  • Ascus:
  • Liquid Growth:


Ecological Traits:

Found in many different agricultural sites, notably vineyards. Also found in the bark of cork oaks.

Distinguishing Features:

Filamentous, other features depend on species

Role in wine:

Fusarium species can be found on the surface of grapes; no role in winemaking.

Fusarium oxysporum is known as fusarium wilt.

Fusarium oxysporum has also been shown to be a high producer of 2,4,6-Trichloroanisole.
