What is a phylum?
Phylum
Phylum Microsporidia is generally included in kingdom Fungi, though its exact relations remain uncertain,[33] and it is considered a protozoan by the International Society of Protistologists[34] (see Protista, below). Molecular analysis of Zygomycota has found it to be polyphyletic (its members do not share an immediate ancestor),[35] which is considered undesirable by many biologists. Accordingly, there is a proposal to abolish the Zygomycota phylum. Its members would be divided between phylum Glomeromycota and four new subphyla incertae sedis (of uncertain placement): Entomophthoromycotina, Kickxellomycotina, Mucoromycotina, and Zoopagomycotina.[33]
