Abstract
Electron microscopic observations on the membrane of the spermatial vesicles in the red algaErythrocystis montagnei are presented. A portion of this membrane is modified and more electron dense, with a layer of microtubules of about 20 nm. Generally, this membrane portion forms two paired bulges, appearing 3-shaped in cross-section. More rarely, two completely separate cylindrical bodies of about 0.3 µm diam. surrounded by membranes have been observed in the spermatial vesicles. The significance of these structures as possible vestigial remnants of flagella is discussed.
