 Description: Hyphae 3.4-8.8 µm in diameter. Dried weight of “+” strain (strain No. 041-3) 0.3714 gm after 5days’ culture. Conidiophores with a primary vesicle from which secondary vesicles produced on short stalks. Secondary vesicles persisting and becoming to funnel shape on the primary vesicle after conidia maturing. Conidia brown, smooth, spherical, 11-15 µm in both of “+” strain and “_” strain. Sporangia oval, smooth, light brown, “+” strain 28-80 × 31-60 µm and “_” strain (strain No. 041-1) 25-78 × 31-63 µm. Sorangiospores light brown, oval, smooth and without appendages on both ends, “+” strain 8-28 µm and “_” strain 11-26 × 10-14 µm. Zygospores 39-87 × 31-82 µm with density of 400-950/cm² on malt extract agar and 37-73 × 31-63 µm with density of 16-115/cm² on potato dextrose agar.

 Note: Choanephora infundibulifera (Currey) Sacc. Choanephora conjuncta Couch and Choanephora cucurbitarum (Berk. & Rav.) Thaxter, can form zygospores among interspecies no matter the morphologies of the sporangiospores and conidia are different with each other (Wu and Chien, 1980).
