Life History:
alternation of heteromorphic phases, with a free-living unicellular sporophyte (previously described as an independent alga, Codiolum gregarium) that produces quadriflagellate zoospores and unisexual filamentous gametophytes that produce biflagellate anisogametes; gametophytes recycling by means of quadriflagellate zoospores; both male and female gametes capable of parthenogenetic development into unicellular stages (Lokhorst and Trask 1981; Hanic 1965; Kornmann 1963b, p. 63; Kornmann 1961a; Kornmann 1961b, p. 42) Display references
