フノリのparasporeに就いて 海藻胞子附けの研究第三報

抄録

Some types of Gloiopeltis furcata and G. tenax have paraspore, and tetraspores on the same frond. Spermatids, carpogons and carpospores are not found in these types. The groups of paraspores are very similar to the cystocarps in appearance, but they are formed asexually. The fronds from paraspores also have paraspores and tetraspores; i. e. in these types no alternation of generations occurs.
