　Description： Colonies on CMA 5.7–5.9 cm diam. in 4 days at 27 ℃, loosely cottony, white, translucent, with rough margins, reverse white. Mycelium spreading, vegetative hyphae hyaline, septate, branched, 2.5–7 μm wide, in the presence of nematodes giving rise to arched or circular hyphae, which at first discrete, then compounded into extensive networks. Conidiophores hyaline, erect, septate, 280–460 μm high, 4.5–7 μm wide at the base, tapering upward to 2.5–3 μm wide, simple, proliferating at the tip to produce up to 12 conidia, with each conidium bearing on a projection of various length of 2.5 to 12 μm long. Conidia hyaline, broadly fusiform, 37.5–42 × 20–22.5 μm, rounded at the apex, pointed toward the truncate base, 3-septate, septa being laid down near two ends, the uppermost septum delimiting a small papilla-shaped cell, the second cell barrel-shaped, much larger than the other cell, 20–33 μm long. Chlamydospores yellowish, globose, 19–25 μm diam.

　Note： This species is characterized by the clustering of up to 12 conidia at the apex of conidiophores. The conidia in M. thaumasium are similar to those of M. eudermatum (Rubner, 1996). However, the length/width ratio is higher of c.a. 2 folds in the former, while lower of c.a. 1.5 folds in the latter.
