The nematode has been captured by the hour-glass-shaped adhesive knobs of the wood-rotting mushroom Hohenbuhelia (N90). There is a lectin in the knob cell that binds chemically to a sugar in the nematode's cuticle (biological crazy glue). The nematode is held fast and, in trying to escape, the hypodermis (inner wall) has been pulled away from the cuticle (outer wall) but to no avail! Nematodes can sometimes escape from the fungus when they are close to moulting and break out of their own skin!
