NOTES ON SOME LITTLE-KNOWN RED ALGAL EPIPHYTES OF JAPAN

Abstract

Studies on one drift macro-alga collected in the winter of 1973, from southern Japan have brought to light several interesting epiphytic algae. This work provides additional distributional record for Japan. Presented in this paper are three algal epiphytes, namely, Antithamnion lherminieri (Crouan) Bornet, Ceramium howei Weber van Bosse and Ceramium tenerrimum (Martens) Okamura. These algae were observed attached to a common host, Sargassum sp., stranded on the shore of Fukiage, Kagoshima Prefecture. The materials used in this study are mounted in glycerine micro-slides and presently kept with the author in the Seto Marine Biological Laboratory.
