- 1. FILUM HYPHOCHYTRIDIOMYCOTA Class hyphochytridiomycetes MATERI KULIAH KE 13 PENGANTAR MIKOLOGI TUMBUHAN
- 2. Classification Hyphochytridiomycetes Order Hyphochytriales ā¢ Family Anisolpidiaceae ā¢ Family Rhizidiomycetaceae ā¢ Rhizidiomyces, Reesia, Latrostium ā¢ Family Hyphochytriaceae ā¢ Hyphochytrium, Cystochytrium, Centeriomyces
- 3. Characteristics ā¢ Hyphochytridiomycetes are aquatic, freshwater or marine chytrid-like fungi ā¢ Motile cells are anteriorly uniflagellate, ā¢ Tinsel type flagellum ā¢ Parasitic on algae, saprobic on plant and insect debris in the waters in which they live. ā¢ The walls of all species contain chitin. ā¢ Cellulose is present in some
- 4. Continueā¦ ā¢ The thallus wich may holocarpic or eurocarpic - in holocarpic species the thallus is endobiotic and is converted into zoosporangium - in eucarpic form the thallus may consist of a single reproductive organ bearing a branched rhizoidal system, or may be polycentric and consist of branched hyphae with some septa. holocarpic eucarpic
- 5. Continue.. ā¢ The zoosporangia are inoperculate and release their zoospores through discharge tubes. ā¢ The zoospora germinate and reproduce the thallus. ā¢ Sexual reproduction is known only in the genus Reesia, whose systematic position is still uncertain and whose morphology requires reinvestigation.
- 6. Rhizidiomyces ā¢ The thallus is monocentric, consisting of a single cell that bears a system branched rhizoids sunken into substratum. ā¢ Sexual reproduction has not been observed ā¢ Example Rhizidiomyces apophysatus
- 7. Life Cycle of Rhizidiomyce s apophysatus ā¢ Parasitic on the oogonis of water molds of family Saprolegniaceae or on the green alga Vaucheria. But, it also Isolated from soil and pine pollen. ā¢Zoospore bears a tinsel flagellum
