Characiosiphon Iyengar
	From Greek charax, "stake" + siphon, "tube"
	Characiosiphon is multinucleate and coenocytic, meaning that the thallus has no transverse cell walls and is siphonaceous. This green alga is found in freshwater habitats.   Characiosiphon has a similar life cycle to Protosiphon but is larger, has multiple discoid plastids, and dwells in aquatic habitats rather than the damp soils or muddy banks where Protosiphon is found. Characiosiphon reproduces through zoospore production.           Cells viewed with dark field optics.
