Fusarium kyushuense O'Donnell & T. Aoki, in Aoki & O'Donnell, Mycoscience 39(1): 2 1998..

 Description: Colonies growing average on Potato Dextrose Agar at 25℃, effuse, red to pale red or yellow red, reverse red, wine red, deep red, pigment secreted. Mycelium partly submerged, partly superficial, composed of branched, septate, smooth, hyaline to light red or pale red, thin-walled hyphae, 2 - 3 μm wide. Conidiophores arising from aerial or surface hyphae, up to 50 μm, often branched. Conidiogenous cells monophialidic, ampulliform or subulate, some proliferating sympodially, hyaline, smooth, 21 - 27 × 3 - 4 μm. Microconidia borne from aerial conidiogenous cell, oblong to clavate, 0-1 septate, hyaline, smooth, 0-septate 8 - 11 × 2.9 - 4.5 μm; 1-septate 13 - 24 × 3.5 - 5 μm. Macroconidia arising from sporodochial conidiogenous cells on surface hyphae, falcate to fusiform, 3 - 5(-6)-septate, most 3-septate, straight to slightly curved, hyaline, often with an acuate apical cell and a distinct or indistinct basal foot cell; 3-septate 21 - 27 × 3 - 4 μm; 5-septate 40 - 52 × 3 - 4.5 μm.

 Note: Fusarium kyushuense is characterized by producing red, winter red to deep red diffused pigments in its colony, also by cushion-shaped sporodochia, which can be easily distinguished from Acremonium. Additional unique feature also included phialidic, proliferating sympodial conidiogenesis. Except morphological similarity, while online blasting NCBI GenBank database, isolate from Taiwan has an rDNA sequence e value=0, and identity index of 97% to F. kyushuense.
