　Description： Colonies on CMA 0.1 cm diam. in 7 days at 27 ℃, densely cottony, white, with entire margins, reverse white. Mycelium spreading, vegetative hyphae hyaline, septate, branched, 2–4 μm wide. Assimilative hyphae permeating within nematodes, 2.5–4.5 μm wide. Conidiophores protruding from dead nematodes, simple, rarely branched, scattered 1–9 septate, 23–280 μm long, 2.5–4.5 μm wide. Conidiogenous cells discrete, lateral, phialidic, verticillately arranged in groups of 2–4 individuals, or occasionally scattered, each phialidic cell globose at base, 4–6 μm diam., provided with one or occasionally two apical necks of 2–5 × 1–1.5 μm. Conidia in clusters of 2–8 on the top of phialidic neck, femur-shaped, 5–6 μm long, and 2–3 μm wide in the middle, with two ends slightly swelling, each swelling usually inequilateral. Arthroconidia can be observed in old culture of more than one month, cylindrical, 14–20 μm long, 3–4 μm wide. Chlamydospores not observed.

　Note： Femur-shaped conidia with a recurved beak at ends are exclusive in H. bysmatosporum and H. diceraeum (Drechsler, 1941). The tip of beak is where the conidium attaches to the conidiogenous cell. As a result, conidia situated on conidiogenous cells are in an oblique position (Fig. B). H. diceraeum differs from H. bysmatosporum in conidia having sharp beaks.
