 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, 2.5–6 μm wide, in the presence of nematodes, giving rise to hyphal arches and loops which at first are discrete, then becoming compounded into networks. Conidiophores hyaline, septate, subulate, erect, simple, 200–325 μm high, 7–9 μm wide at the base. Conidiogenous cells integrated, terminal, simple, or branched and giving an candelabrum-form appearance, sympodial, geniculate, denticulate, bearing up to 12 conidia, denticles oblong, 1.5– 2.5 × 1.5–2 μm. Conidia hyaline, narrowly obovoid, 19–27 × 11–15 μm, 1-septate below the middle, slightly constricted at the septum, the lower and smaller cell 10–14 μm long. Chlamydospores not observed.

 Note: The conidia were reported to be 22–35 × 7–11 μm in A. javanica (Rifai & Cooke, 1966). The materials from Taiwan have shorter and broader conidia. This minor difference does not justify the creation of a new species. This fungus is therefore tentatively attributed to A. javanica.
