Most appear closer to the animals than to the fungi, and they are of great interest to biologists studying animal origins. The chytrids have also been included among the Protista, but are now more often placed among the Fungi. Orders Chytridiales Spizellomycetales Blastocladiales Monoblepharidales Neocallimasticales Chytridiomycota is a division of the Fungi kingdom and contains only one class, Chytridiomycetes. ...

It has been suggested that the nucleariids are in fact a sister group to the fungi, and that the rest of the classes form a monophyletic or paraphyletic sister group to the animals.
