The fine structure changes of a high producing Claviceps paspali strain during submerged cultivation were followed by means of different electron microscopy techniques. Considerable changes in ultrastructure have been found between the vegetative and the production mycelium particularly in the 4‐day‐old production mycelium. In this state freeze‐fracturing micrographs reveal a number of “section” vesicles and vacuoles mediating communication between the growing and producing cells and the external milieu. Abundant signs of secretory activity on the plasma membbrane are possible sites of alkaloid secretion.
