Sixteen new mutants of the biflagellate green alga Chlamydomonas reinhardtii with either stumpy‐flagella or no flagella at all were examined by electron microscopy. Four of the mutants were found to carry short bulbous flagella containing amorphous electron‐dense material which may represent unassembled flagellar protein. Basal bodies of normal ultrastructure were present in all mutants. Dikaryon dominance tests indicated that the stumpy mutations were recessive to wild‐type in all cases tested. Stumpy mutations also conferred a measure of detergent resistance to Chlamydomonas , apparently by affecting the detergent‐solubility of the flagellar membrane.
