　Note： Choanephora conjuncta Couch, Choanephora infundibulifera (Currey) Sacc. and Choanephora cucurbitarum (Berk. & Rav.) Thaxter, can form zygospores among interspecies (Wu and Chien, 1980). Sizes of zygospores formed from C. conjuncta with C. infundibulifera and C. cucurbitarum were respectively 43-51 × 41-56 µm and 23-65 × 39-61 µm.
