Chytridiomycetes are zoosporic fungi living mostly in freshwater or soil but some species are marine. They are saprobic or parasitic. The hosts of parasitic species are varied such as algae, land plants, animals and fungi. Batrachochytrium dendrobatidis (Rhizophydiales) causing a famous infectious disease of amphibians, chytridiomycosis, is an only species that is parasitic on vertabrate. This chytrid is contributing to a worldwide decline in amphibian populations. Synchytrium endobioticum (incertae sedis) causes the potato wart disease (black scab) and serious commercial damages.

Thalli of the Chytridiomycetes are monocentric or rhizomycelial polycentric. The flagellate cell possesses a centriole and microbody-lipid globule complex. Asxual reproduction by uniflagellate zoospores. Sexual reproduction by isogamy or anisogamy but not oogamy.
