Fusarium babinda sp. nov. is described and illustrated. Fusarium babin
da was isolated from soils and plant debris in soils associated with r
ainforest and wet sclerophyll forests in eastern Australia. The key fe
atures of this species are the formation of microconidia in proliferat
ing polyphialides and the production of chlamydospores. Fusarium babin
da can be distinguished from F. subglutinans by the presence of chlamy
dospores and the production of larger five-septate macroconidia, compa
red to three-septate macroconidia in F. subglutinans. The fungus is di
fferentiated from F. polyphialidicum by the shape and nature of the ma
croconidium which is smaller and has thinner walls, the production of
larger microconidia and the production of violet pigments in agar.
