SUMMARY Electron microscope observation revealed the presence of many fine filaments within the cytoplasm surrounding the leading edge of the septum in telophase cells of Spirogyra verruculosa Jao. These filaments, about 7 nm each in diameter, ran parallel to one another along the leading edge of the septum and, sometimes, they appeared to be gathered into at least two bundles. These filament distribution patterns coincided well with those of the fluorescence of rhodamine‐labeled phalloidin in the vicinity of the septum in telophase cells. The present results suggest that the fine filaments observed within the cytoplasm surrounding the leading edge of the septum may be actin filaments.
