It is said that the seed of Porphyra tenera KJELLM. (Asakusanori) in culture ground appears in more abundance or in earlier time when the water is salty So we studied on the influence of the sea water of various concentration on the formation of sporangium and the liberation of spore in the Conchocelis-phase. The results are as follows: 1) The growth of Conchocelis gets worse in dilute sea water than in the normal. The branching of filaments becomes scanty in low concentrated water. 2) The formation of sporangia is delayed in dilute sea water than in the normal in the beginning, but afterwards many sporangia are formed. 3) The liberation of the spore decreases in dilute sea water than in the normal.
