Lacking a satisfactory system of classification and identification with which to organise these many, seemingly similar "Fusarium" species, the mycologists Snyder and Hansen collected samples of various fusaria from laboratories worldwide, isolated single spores and cultured them for subsequent analysis of their genetic variation. Their work indicated the existence of 9 distinct species of "Fusarium", but there have since been several different classification systems that reach different conclusions, and consensus around this has been difficult to establish, perhaps in part because research focuses predominantly on the agriculturally or botanically more significant fusaria. "F. sporotrichioides" exemplifies these classification difficulties, as it is usually designated as belonging to the section Sporotrichiella, along with other similar species such as the more well-studied "F. poae" and "F. tricinctum", although other classification systems have placed "F. sporotrichioides" in the "Arthrosporiella" section, based on the similarity of its conidial morphology to other species in the section.
