Phylum: CHYTRIDIOMYCO
These
organisms, commonly called "chytrids", are aquatic or live in damp
soil. Many are parasitic on algae, fungi, mosses, and higher plants.
The
primitive Members of the division Chytridiomycota have unicellular form (entirely converted into a
reproductive sporangium) while the higher have both broad true hyphae and
narrow rhizoids. Their cell wall composition is mostly chitin,
and cellulose is not known to occur. This division has been classified with the
true fungi even though flagellated spores and gametes are produced. Gametes and
zoospores have a single, posterior whiplash flagellum. Sexual
reproduction is variable and may be isogamous, anisogamous or oogamous. The
division has a single class, the Chytridiomycetes
Order: Chytridiales
