Abstract

Nematode-trapping fungi constitute a guild of species that develop specialized trapping structures with which they capture and digest nematodes. These traps are not constitutively present, but instead develop in the presence of nematodes3; they attract them2, adhere to their cuticle and eventually pierce it, extending hyphae inside their bodies.
