Fusarium solani

The Fusarium solani species complex (FSSC) is a group of filamentous fungi in the division Ascomycota, family Nectriaceae. Members are common soil-inhabiting molds. Members of this group are implicated in plant diseases as well as in serious human diseases such as fungal keratitis. This species complex includes at least 50 species. They were originally all considered a singular species Fusarium solani on the basis of morphology, until genetic methods that were able to differentiate between them were developed. Each of them has genetic characteristics that justify their distinction from another, reflecting adaptations to different hosts and habits. For example, the actual Fusarium solani is not associated with bean root rot. Nevertheless, due to the difficulty of distinguishing them without using genetic methods, non-taxonomic sources tend to still call all of them F. solani, sometimes with additional infraspecific designations such as forma and forma specialis.
