Fungi imperfecti reproducing fungi is the subject of ongoing debate in the mycological community. These groups are no longer formally accepted because they do not adhere to the principle of monophyly. The taxon names are sometimes used informally. In particular, the term 'hyphomycetes' is often used to refer to molds, and the term 'coelomycetes' is used to refer to many asexually reproducing plant pathogens that form discrete fruiting bodies. Following, a classification of the Fungi imperfecti: Saccardo et al.(1882-1972) Other, according to Dörfelt (1989): Other systems of classification are reviewed by .
