Life History:

potential alternation of heteromorphic phases, with zoospores from unilocular sporangia on macroscopic sporophytes germinating to produce much branched prostrate filaments bearing uniseriate to biseriate plurilocular organs, subcultures of which produced successive generations of loosely branched filaments bearing plurilocular organs; syngamy not observed; macroscopic sporophytes (blades) not obtained in culture (Wynne 1972a, p. 134)
