The chytrids are the simplest and most primitive Eumycota, or true fungi. Molecular studies now firmly place the Chytridiomycota within the fungal kingdom. Chytridiomycota in being heterothallic (apparently existing as morphologically similar, male and female strains). Berger, L, A. Hyatt, R Speare y J. Longcore (2005) Life cycle stages of the amphibian chytrid Batrachochytrium dendrobatidis. Chytridiomycota are unusual among the Fungi in that they reproduce with zoospores.

The thalli of these fungi are typically microscopic and varied. ... sexually, survive? Mycelium of Basidiomycetes: The well developed, filamentous mycelium consists of a mass of branched, septate hyphae generally spreading in a fan-shaped manner. a sporic life cycle, with a multicellular haploid and diploid thallus is produced during its life cycle. The production of asexual and sexual spores at different times during the life cycle of a fungus is of selective value, with asexual reproduction normally occurring at optimal conditions and sexual reproduction occurring when conditions are less favorable. Most are parasites of algae and animals or live on organic debris (as saprobes). Sexual reproduction. pythiensis) was later discovered in a species of (Sarkar Pythium and Dayal, 1988).
