FUSARIUM-SCIRPI - EMENDED DESCRIPTION AND NOTES ON GEOGRAPHIC-DISTRIBUTION

Several unusual cultures of Fusarium spp. were recovered from plant debris washed from soil samples from broken Hill, Australia, in 1976 and 1977. Since the initial isolations, many more of these cultures have been recovered in other areas in eastern Australia and in the Cape Province, Republic of South Africa, and the Republic of Transkei. Although these cultures have several characters in common with F. equiseti, they are not typical of F. equiseti, and are identified here as F. scirpi. The original description of F. scirpi is emended to include only those isolates that produce fusiform, obovoid, allantoid and combinations of these shapes, 0-3 septate microconidia on characteristic polyphialides.
