SUMMARY Tetrahedral tetrasporangia of several florideophycean red, algae were examined with the electron microscope for details of meiosis. Only telophase II nuclei are described since earlier stages were not, observed. Both divisions of meiosis are presumed to occur within the confines of the original tetrasporangial mother cell nuclear envelope. Four nuclei are then formed simultaneously. These observations essentially support Yamanouchi's description of telophase II in Polysiphonia flexicaulis (Harvey) Collins (as P. violacea) and suggest that meiosis in these algae could be basically similar to “uninuclear meiosis” in the fungi Saprolegnia and Saccharomyces .
