Summary This study explores natural ionic currents traversing hyphae and sporangia during the asexual life cycle of the mycelial water moldAchlya debaryana. Ionic current enters the extending hyphal apex at a density of 1–2μAcm−2 in the form of current spikes. Current normal to the surface enters hyphae up to 600 μm behind the growing tip. A large efflux of current lasting 1–2 minutes occurs during the homogeneous stage of sporangium development. Spore release is accompanied by a few spikes of inward current. The results obtained so far suggest that the developmental processes of hyphal elongation and sporangium formation in the asexual life cycle of water molds are correlated with particular ionic currents.
