抄録

Lagenisma coscinodisci, an endobiotic parasite of the centric diatom Coscinodiscus granii produces typical biflagellate zoospores. The special feature of the surface structures of these zoospores is that the lateral hairs on the tinsel flagellum narrows abruptly to form very fine tips. There are a number of interesting structures, described as X-bodies present near the periphery of the zoospore body. These bodies consist of distinct outer and inner parts and have structural similarities with ‘Rohr’ and ‘Stachel’ demonstrated by Keskin and Fuchs (1969) associated with the infection of Polymyxa betae.
