抄録: The life history of Gloioderma iyoensis Okamura was studied in laboratory culture. The materials were collected at Hario-strait, mouth of Omura Bay, western Kyushu, where this alga is annually seen, appearing in March-June and matures in April-June. The culture studies were carried out under 20-22℃, 2000 lux and 12: 12hr (L: D). Tetraspores obtained from field-collected plants grew into prostrate discs. When the discs reached to about 400μm in diameter, erect fronds grew from the center of discs. The erect fronds developed into dioecious Gloioderma plants which produced either spermatangia or cystocarps. The carpospores liberated from culture female plants grew to erect fronds in a pattern similar to that of tetraspore germlings. The erect fronds from carpospores produced tetrasporangia. Thus, the life history pattern of Gloioderma iyoensis is fundamentally identical to a Polysiphonia-type.
