Nematode Attacked by Dactyllelina candida

In Dactyllelina candida the knob-shaped trapping devices are adhesive,  stick to the nematode's cuticle and hold the victim fast (see below).   The knobs can also be deciduous and break off from the support stalk during a nematode's struggle to escape.  In the SEM above, we see two deciduous knobs attached to the nematode.  The black arrows show the scar left when the knob broke away from the parent support stalk.   The red arrows show the thick pad of adhesive material that has developed to 'glue' the knob to the victim.   The knob is a living cell and will use the adhesive anchor as a base from which it will penetrate through the nematodes cuticle to the soft tissues within.    Within 24 h The fungus cant proliferate its assimilative hyphae inside the host, digest the contents and translocate material elsewhere for growth, additonal trap production, or spore reproduction .
