The ability to capture nematodes is connected with a spe- cific developmental phase of the fungal mycelium (Table 1, Figure 1). The trapping (predatory) fungi have developed so- phisticated hyphal structures, such as hyphal nets, knobs, branches or rings, in which nematodes are captured by ad- hesion or mechanically. The endoparasites, on the other hand, attack nematodes with their spores, which either ad- here to the surface of nematodes or are swallowed by them. Irrespective of the infection method, the result is always the same: the death of the nematode. Examples of the first group (Table 1) are Arthrobotrys spp., such as A. oligospora, A. conoides, A. musiformis and A. superba, which all form three-dimensional adhesive nets, whereas A. dactyloides uses constricting rings to capture nematodes mechanically by the swelling of the ring cells. Adhesive branches and adhesive knobs appear in the genus Monacrosporium. M. haptotylum (Dactylaria candida) produces both adhesive knobs and nonconstricting rings.
