Fungi imperfecti

Fungal classification based on asexual characteristics

Fungi imperfecti

The fungi imperfecti, also laterally called Deuteromycota, Deuteromycetes or imperfect fungi are fungi which do not fit into the commonly established taxonomic classifications of fungi that are based on biological species concepts or morphological characteristics of sexual structures because their sexual form of reproduction has never been observed. They are known as imperfect fungi because only their asexual and vegetative phases are known. They have asexual form of reproduction, meaning that these fungi produce their spores asexually, in the process called sporogenesis.
