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.
