Two strains of Fusarium sinensis sp. nov. were isolated from the seeds and roots of wheat (Triticum aestivum L.) in Shandong Province, China. They are superficially similar to F. dlaminii in producing fusiform-to-reniform and napiform microconidia and chlamydospores in almost the same size range as F. dlaminii. However the colonies and chlamydospores of F. sinensis resemble those of species in sections Roseum, Gibbosum and Discolor. Phylogenetic analysis of partial translation elongation factor 1 (EF-1) sequence data indicates that F. sinensis is closely related to but distinct from the F. avenaceum/F. tricinctum/F. acuminatum species complex.
