Summary Sporangial development in the zoosporic fungusAchlya intricata has been studied using light microscopy, a plasmolytic technique, KCl-filled microelectrodes and ion-selective microelectrodes. The completion of cleavage (spore delimitation) is accompanied by a change in appearance of the sporangium, loss of turgor and membrane potential, decrease in volume and release of K+. The measured loss of K+ is in agreement with previous measurements of extracellular ionic currents around developing sporangia ofAchlya using a vibrating probe. The relationship between these changes and the mechanism of spore liberation is discussed.
