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 mostlychitin,
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
