ResumoABSTRACT Laurencia brachyclados Pilger from Hawai'i completed a “ Polysiphonia ‐type” tri‐phasic life history in 21 weeks in laboratory culture. Tetraspores developed into gametophytes in a nearly 1:1:1 ratio of females: males: non‐reproductive. Carpospores were released as early as 21 days after mixing virgin female and male gametophytes. Cultured thalli showed a “guerilla type” growth form. Other Hawaiian Laurencia species in culture had longer maturation times or remained non‐reproductive. Variation in life history schedules may influence Laurencia species coexistence and algal community structure.
