Conidiophores colourless, erect, bearing a single terminal spore (conidium). The conidia have 2 to several cells, are colourless, and have one cell larger than the others. Because of the large cell, the conidia are strongly spindle-shaped. Rubner (1996) recognized 39 species. Predacious on eelworms, which they catch by means of sticky knobs (a), rings (b), or adhesive networks (c). Occurring in soil, dung, and decaying plant matter. Holomorphs unknown.
