A Feulgen microspectrophotometric analysis of successive generations of Fritschiella tuberosa Iyengar revealed an asexual repeating of one generation rather than an obligate alternation of isomorphic generations as previously described. F. tuberosa regularly reproduces asexually by the release of one quadriflagellate zoospore produced/cell in all parts of the upright and prostrate portions of the thallus. In the vegetative thalli, nuclei in the G 1 (pre‐synthesis), synthesis, and G 2 (post‐synthesis) phases of the mitotic cycle are all well‐represented.
