(System of anamorphs according to SACCARDO 1886)

Mycelial growth speed and density of Dactylaria candida are comparable to Arthrobotrys dactyloides, but its mycelium is perceptibly more delicate.
The conidiophores of Dactylaria candida bear on their top groups of 5-7 multicellular, spindle-shaped conidia whose central cell is larger than those at the base and on the tip.
Dactylaria candida develops two types of traps: 15-23 µm large non-constricting rings on 10-35 µm long stalks, and 4-7 µm long, 3.8-6 µm broad adhesive knobs on 4-15 µm long stalks (DRECHSLER 1937). The knobs and rings tend to be detached by the resistance of the captured nematodes, which does not prevent them from an infection of the prey (BARRON 1975; DOWSETT & REID 1977).
