|How many species of the Fusarium head blight fungus are there?|
|Eleven phylogenetic species are now recognized within the Fusariumgraminearum species complex (Starkey, et al., 2007. Fungal Genetics and Biology doi:10.1016/j.fgb.2007.03.001). Species are often limited to particular regions of the world, although the origin of many of these species, including Fusariumgraminearumsensu stricto remains uncertain.|
