Chytridiomycota in being heterothallic (apparently existing as morphologically similar, male and female strains). sexual or asexual. The only diploid (2N) phase in the life cycle is the zygospore, produced through the conjugation of compatible gametangia during the sexual cycle (see Figure 2A, B). mating.

Chytridiomycota is a phylum in the kingdom Fungi.The name is derived from the Greek chytridion, meaning "little pot", describing the structure containing unreleased zoospores.In older classifications, chytrids (except the recently established order Spizellomycetales) were placed in the class Phycomycetes under the subphylum Myxomycophyta of the kingdom Fungi. Current living members are placed in four major major sub-groups recognized at the Division (Phylum) level as indicated by the ending "-mycota": The cell wall is chitinous in nature.
