Abstract
Isolates of Fusarium nygamai were mated and produced fertile perithecia of Gibberella nygamai sp. nov., on carrot agar. Female-fertile tester strains were recovered from random ascospore progeny and two were identified as more reliable female parents in the detection of other members of this population. The formation of microconidia in short chains and the formation of chlamydospores in anamorph progeny cultures are suitable characters for species identification of F. nygamai. Fusarium nygamai is predominantly soilborne.
