Pronunciation: fun'ji im'per-fek'ti
Definition: A phylum of fungi in which sexual reproduction is not known or in which one of the mating types has not yet been discovered. Formerly, most fungi causing disease in humans were considered asexual and were placed in this class, but studies have revealed that many are not imperfect and that in their sexual forms they can be classified as ascomycetes or basidiomycetes.
See: imperfect fungus
