Which phylum is a group of miscellaneous fungi that don’t fit into the other three categories? Zygomycotes Deuteromycotes Ascomy
DaniilM [7]

Answer:

Deuteromycotes

Explanation:

Kingdom Fungi consist of eukaryotic organisms grouped into 3 phyla, with one group that doesn't fit into any of the grouped three. Each group of fungi were classified into phylum based on their reproductive life cycle. The three phyla are Zygomycotes, Ascomycotes, Basidiomycotes.

Zygomycotes produce their spores by meiosis in a structure called Zygosporangium. Ascomycotes produce their spores via meiosis in ascus (sac-like). Basidiomycotes produce their own spores via meiosis in club-like basidium.

However, a fourth group exists that has no known sexual reproductive structure (meiospores), instead it is known to reproduce asexually via mitospores. This group is called DEUTEROMYCOTES or commonly known as FUNGI IMPERFECTI. It is a group of miscellaneous fungi that doesn't fit into the classification basis of the other three phyla.
