The natural occurrence of perithecia of Gibberella coronicola T. Aoki & O’Donnell, the cause of crown rot of wheat, on wheat residues in the Moree district of New South Wales is reported. Cultures established from single ascospores taken from fertile perithecia of the fungus produced its anamorph, Fusarium pseudograminearum O’Donnell & T. Aoki. The morphology of the fungus is compared with published descriptions of perithecia produced in crossing experiments in culture. No differences were observed in the morphology or the dimensions of the fungus from the two sources. Additional keywords: Fusarium pseudograminearum, Ascomycete.
