'Fungi imperfecti' includes
The fungi imperfecti or imperfect fungi, also known as deuteromycota, 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; hence, the name "imperfect fungi." Only their asexual form of reproduction is known, meaning that this group of fungi produces their spores asexually, in the process called as sporogenesis. Thus, the correct answer is option A.
