I found good resource to illustrate how a certain fungi capture its prey for food. This is good
defence against nematodes that may invade the plant roots. There is a animation to illustrate how Nematophagus Fungi capture its prey.

Arthrobotrys dactyloides shows significantly slower and denser hyphal growth than most network-developing species like A. superba and A. oligospora. On the top of its upright, unbranched, 200-400 µm high Conidiophores it bears groups of 4-10 two-celled, elongated ellipsoid, slightly curved, 32-45 µm long and 6-10 µm broad conidia on about 5µm long sterigmata. The two cells of one conidium are of about the same size. Older cultures develop separate, yellow, spherical, up to 15 µm large chlamydospores

It is the only species of its genus besides Arthrobotrys anchonia that develops constricting rings, which
