The Subdivision Deuteromycotina is also known as the Fungi Imperfecti or the anamorphs. This group of fungi lacks a sexual stage in their life cycle, which makes them difficult to classify. Some synonyms for this subdivision include Hyphomycetes, Mycelia Sterilia, and Conidial fungi. Hyphomycetes refers to their filamentous growth, while Mycelia Sterilia describes their lack of sexual reproduction. Conidial fungi refers to the asexual spores produced by this group. Despite the confusion surrounding their classification, Deuteromycotina includes several important plant and animal pathogens, as well as some species used in industrial and biotechnological applications.
