Life History:
not completely known for Pacific coast populations, but probably same as in Europe, where unisexual spherical gametophytes (Halicystis ovalis); alternate with a siphonous sporophyte (Derbesia marina) by means of biflagellate anisogametes and stephanospores (Kornmann 1938); Neumann 1974; Neumann 1969b; Neumann 1967 Display references
