The 2- to 4-celled colourless spores (conidia) are produced at the "joints" of more or less zigzag or geniculate conidiophores. The youngest conidium is at the top and new growth of the conidiophore then originates just below it and pushes it to one side. Considered by some authors to be indistinguishable from Arthrobotrys. Predacious on eelworms, which they trap in sticky networks of loops. Occurring in soils high in organic material. Holomorph unknown. Ref: Rifai 1975; Rifai and Cooke 1966; Rubner, 1996
