Abstract
The macroscopic colonies ofTetrasporopsis fuscescens consist of a tegument of irregularly folded bag-like mucilage. It contains isolated ellipsoidal cells arranged in a regular peripheral stratum and rather sparsely and irregularly beneath. They show polarity, 4 parietal chromatophors when fully developed, have a wall containing cellulose, and no contractile vacuoles. Naked protoplasts are released from them through circular openings oriented towards the surface. Flagellated cells and cysts were not observed.T. reticulata may be closely related toT. fuscescens, but probably no other species is allied.
