"Fungi imperfecti' includes a. Only asexual forms b. Non-parasitic forms c. Motile gamete forming fungi d. None of the above
Hint: Fungi imperfecti, are also called as imperfect fungi, and they are commonly known as Deuteromycota, generally, the fungi have a taxonomic classification based on the morphological characteristics and biological species concept, but this fungi imperfecti do not for into any of the taxonomic classification.
Complete answer: > This fungus is not fit into any classification because no sexual reproduction is observed in this fungi, and the reproduction takes place only by asexual form such as spores.
> In general, the fungi classification is based on the characteristic of the fruiting body and also by the spores produced during sexual reproduction, so because of this reason, most of these fungi do not get any place in the modern classification.
> Normally in the phylogenetic classification, phylogenies may be used for the relationship between asexual reproducing fungi with sexually reproducing fungi. Because of this method, now many of the asexually reproducing fungi are placed into the tree of life.
> Phylogenetic methods generally require sufficient quantities of the biological species such as spores, or specimens, that too from fresh or pure fungal cultures, but in this many asexual species do not know the exact relationship of these fungi with other species. The term Telomorph is not applicable to the fungi that lack the sexual forms.
Hence, the correct answer is option (A).
Note: Long back ago, this fungi imperfecti also had a classification, but this is no longer used, where Hyphomycetes are referred for molds, whereas Coelomycetes are referred for asexually reproducing bacteria which have a fruiting body.
