Summary
The pusule system ofGymnodinium spec. consists of tubes formed by the invaginated plasmalemma which is ornamented with delicate ribs on its luminal surface and tightly surrounded by a special, perforated cisterna. The degeneration of the pusule, the fine structure of the theca with some peculiar structures (trichocyst-like vacuoles, collared pits, the developing cyst wall), the stigma and its connection with the flagellar base, and the Golgi apparatus with different types of vesicles are described.
Zusammenfassung
Das Pusulensystem vonGymnodinium spec. besteht aus röhrenförmigen Invaginationen des Plasmalemmas mit zarten Rippen auf der Lumen-Seite, die eng von einer besonderen, perforierten Zisterne umschlossen sind. Die Degeneration der Pusule, der Feinbau der Theka mit Trichocysten-ähnlichen Vesikeln und Kragengruben, die Bildung der Cystenwand, das Stigma und seine Verbindung mit der Geißelbasis und der Golgi-Apparat mit verschiedenen Vesikeltypen werden beschrieben.
