Trap types of predaceous nematophagous fungi

Adhesive columnar branch of Monacrosporium cionopagum

Adhesive columnar branches

One- to three-celled hyphal branches covered with adhesive substance. Sometimes developing meshes or ladders.
Three-dimensional network of Arthrobotrys oligospora

Adhesive three-dimensional networks

Covered with adhesive substance. Loop diameter 20-59 µm. High trapping quota in vitro because of their three-dimensional structure.
Constricting ring of Arthrobotrys dactyloides

Constricting rings

Stalked, three-celled rings. Diameter 20-50 µm. Cells expand towards the inner side when touched there and ensnare the prey, rotifers and protozoa as well as nematodes. - Trapping Mechanism (Animation) !
Non-constricting ring of Dactylaria candida

Non-constricting rings

Stalked, three-celled rings. Diameter 20-50 µm. Prey is entangled when trying to pass.
  • Dactylaria candida (besides adhesive knobs)
  • Dactylella leptospora (besides adhesive knobs)
Adhesive knob of Dactylaria candida

Spherical or oval adhesive knobs

Multinuclear syncytia covered with adhesive substance. Diameter 6-10 µm. On 1-3-celled, non-adhesive stalks.
  • Dactylaria candida (besides non-constricting rings)
  • Dactylella leptospora (besides non-constricting rings)
  • Monacrosporium ellipsosporum
Hourglass-shaped adhesive knob of Hohenbuehelia petalodes

Hourglass-shaped adhesive knobs

Multinuclear syncytia covered with adhesive substance. Diameter 12-20 µm. On sterigmata (short, non-cellular stalks). Very adhesive.
Teleomorphs Hohenbuehelia / Resupinatus with anamorph (Form genus) Nematoctonus, examples:
