Deuteromycota n 1: large and heterogeneous form division of fungi comprising forms for which no sexually reproductive stage is known [syn: {Deuteromycota}, {subdivision Deuteromycota}, {Deuteromycotina}, {Fungi imperfecti}, {subdivision Deuteromycotina}]
Fungi Imperfecti \Fun"gi Im`per*fec"ti\, pl. [L. imperfecti imperfect.] (Bot.) A heterogenous phylum of fungi which lack a sexual phase, or of which the sexual phase is not known. Some undoubtedly represent the conidium stages of various Ascomycetes. It is not considered a natural phylum, and is also called the {Deuteromycota}. The group is divided into the orders {Sph[ae]ropsidales}, {Melanconiales}, and {Moniliales}. It includes the genera {Penicillium} and {Aspergillus}, which reproduce asexually by means of conidia.
