Abstract: In this work, the authors observed the growth and spore-formation of the Concho celis-phase of Porphyra tenera cultured in the lime stone. And then, the spores from the Conchocelis-phase were fixed to the collectors (bomboo twigs) in vessels, in which the lime stones with Conchocelis-filament were placed at the bottom, and the collectors were swung with the motor. Results were summarized as follows: 1) On the surface of lime stone, the germling of the carpospores penetrates into the inner layer and grows up to Conchocelis-filament as like as the case in oyster shell. 2) The penetrating germling develops fundamentally into radiate filaments as in shell, but the filaments are more irregular in shape and they penetrate shallow erly than in shell. 3) The spore-formation and its liberation are also almost similar to the case of shell. Thus, the spores from the Conchocelis-phase were fixed artificially to the collectors and the number of buds of Porphyra were counted under microscope (Table 1). After 45 days culture in the sea, some of buds grew up to adult fronds bearing carpospores.
