Fusarium nisikadoi, a new species from Japan

A new species of Fusarium, F. nisikadoi, isolated from Phyllostachys nigra var. henonis (bamboo) and Triticum aestivum (wheat) in Japan, is described, illustrated and discussed. This species is differentiated from other known species of the genus by the following characteristics: whitish colony color, long zigzag-like chains of 0–3(–5)-septate clavate conidia, intermixed with pyriform conidia, produced mostly from monophialides and rarely from polyphialides in the aerial myceliurn, very long and slender sporodochial conidia, and no chlamydospores. The long chains of septate conidia are known only in this species of the genus Fusarium. The conidiophores on the aerial mycelium sometimes proliferate sympodially. The species is tentatively placed in the form-section Liseola.
