Abstract
Certain nematode-trapping Deuteromycetes form ring-shaped traps with a mechanical function. Touched by a nematode or stimulated artificially - e. g. by heating - the ring-cells swell and capture the nematode. The swelling is documented by slow-motion sequences, details are shown by means of electronmicrographs. The further course of infection events is shown by time-lapse sequences.
