2. • Production of motile cells
(Zoospores or planogamets)
• Have single posterior Whiplash flagellum
• Flagellum attached on the blepharoplast
• Aquatic fungi
• Saprophytes or parasites on aquatic organism
• Some in habitat on soil (Saprophytic or parasitic on
economically important plants) eg. Synchytrium
endobioticum, that causes wart disease in
potatoes

3. • Most of them are unicellular
• Vegetative body consists of single cell
• Holocarpic (At maturity the entire cell converted into
reproductive structure) Eg. Olpidium, Micromyces,
Rozella
• Some Eucarpic (some portion of the thallus converted
into reproductive structures)
• Branched Rhizoid system Eg. Rhizophidium
• More extensive Hypha like rhizoidal system called
rhizomycelium Asexual reproduction takesplace
by zoospore produced by sporangia
https://archive.bio.ed.ac.uk/jdeacon/microbes/chytrid.htm
4. • Zoospores released from the sporangium through porea on the wall
through discharge tube (inoperculate sps)
• Sexual reproduction is only few sps
• Isogamous or anisogamous
• In some sps sexual reproduction is Oogamous- Eg. Monoblepharides

6. Chytridiales
• Small order
• Two genera
• Hapochytrium
• Oedogoniomyces

7. Blastocladiales
• Vegetative body is a typical mycelium
• Sexual reproduction is or aniso-
planogamous.
• The sporangia are thick-walled and
resistant.
• The zoospores has no refractive oil
globule but has a nuclear cap. It swims
evenly.
• Family Hypochytriaceae belongs to
this order

8. Monoblepharidales
• Typical mycelium
• Sexual reproduction is
heterogamous
• Motile male and non-motile
female gamets
• Resistant sporangia is
lacking
