| Description： |
Colonies on CMA 5.8–6 cm diam. in 4 days at 27 ℃, loosely cottony, white, translucent, with rough margins, reverse white. Vegetative hyphae hyaline, septate, branched, 3.5–12 μm wide, in the presence of nematodes giving rise to arched or circular hyphae which at first are discrete, and later frequently compounded into more or less extensive networks. Conidiophores erect, septate, frequently branched, 110–270 μm long, 4–7 μm wide at the base. Conidiogenous cell integrated, terminal, sympodial, geniculate, denticulate, bearing up to 8 conidia, denticles 2–2.5 μm wide, separate or in clusters at the apex. Conidia holoblastic, hyaline, obovoid, 22–30 × 12.5–17 μm, one-celled, with a small truncate protuberance at the base. Chlamydospores hyaline, smooth-walled, spherical to elongate-ellipsoidal, 24–45 × 20–24 μm, usually intercalary, occasionally single or in chains. | |||

| Note： |
A. amerospora is characterized by obovoid one-celled conidia with papillate protuberance at the base. A. botryospora (Barron, 1979) shares the common characters of conidia with A. amerospora. However, A. amerospora differs in having chlamydospores and frequently branched conidiophores. | |||
