Life History:

potential alternation of heteromorphic phases, with zoospores from unilocular sporangia on macroscopic sporophytes germinating to produce tufts of diffusely branched filaments bearing plurilocular organs, subcultures of which produced successive generations of presumed plethysmothalli bearing both unilocular and plurilocular organs; macroscopic sporophytes not obtained in culture (Wynne 1972a, p. 133)

Phenology:

macroscopic plants produced at the same time (May) at all latitudes
