Thielaviopsis basicola is a soilborne fungus that belongs to the Ascomycota division of the "true fungi" and is a hemibiotrophic parasite. [3] Fungi belonging to Ascomycota are known to produce asexual and sexual spores, however, a sexual stage has yet to be observed and validated in the Thielaviopsis basicola life cycle, which classifies this species as one of the Deuteromycete or an ...
