SUMMARY The acetolysis resistant mesospore walls of Spirogyra were investigated by infrared spectrometry and chromic acid degradation. It was demonstrated that the mesospore wall contains chromic acid and hydrofluoric acid resistant sporopollenin. The biological significance could be a protection of the spores against desiccation and fungal attack.
