Abstract Four unialgal strains of the freshwater coccoid red algaPorphyridium aerugineum Geitler were cultivated under laboratory conditions. Cell morphology was studied with the light microscope. The cell surface was examined by means of electron microscopy in order to contribute to the knowledge of polysaccharide sheaths and cytoplasmic membranes. Optimum growth conditions were determined. The range of cell sizes and the average dry masses of single cells were compared in all four strains cultivated at exactly defined temperatures and irradiances. Photosynthetic pigment maxima were measured in intact cells. The red-coloured phycobiliprotein phycoerythrin was not found in any of the examined strains.
