Monacrosporium lysipagum (Drechsler) Subram., J. Indian bot. Soc. 42: 293. 1964.

Basionym: Dactylella lysipaga Drechsler, Mycologia 29: 503. 1937.

 Description: Colonies on CMA 3.7–3.8 cm diam. in 7 days at 27 ℃, densely cottony, white, with entire margins, reverse white. Mycelium spreading, vegetative hyphae hyaline, septate, branched, 2–4.5 μm wide, in the presence of nematodes, giving rise to lateral stalks, stalk filiform, 10–29 × 1–1.5 μm, composed of one or more cells, terminating in a globose adhesive knob of 5–6 μm diam., or a circular ring, the ring 18–20 μm diam., composed of 3 arcuate cells of 2.5–3.5 μm wide. Conidiophores hyaline, septate, erect, 163–250 μm high, 2.5–4 μm wide at the base, tapering upward to 1.5–2 μm wide, the apex at first simple with a terminal conidium, then proliferating to appear up to 3 short projections, each bearing a single conidium. Conidia hyaline, fusiform, 38–52 × 6–12 μm, pointed at two ends, the apex more acute, truncate at base, 4-septate, occasionally 2–3 septate. Chlamydospores not observed.

 Note: Conidia of M. lysipagum are indistinguishable from M. haptotylum. However, these two species can be separated by the length of conidiophores and the type of nematode-trapping devices, being shorter conidiophores of up to 250 μm high and producing both non-constricting rings and knobs in M. lysipagum, while longer conidiophores of up to 350 μm high and only adhesive knobs in M. haptotylum.
