Syncephalis cornu van Tieghem & Le Monnier, Ann. Sc. Nat. 5. ser. 17: 346. 1873.

 Description: Vegetative mycelium on Mucor sp. slender, about 1 µm wide, smooth, hyaline, running over the host. Sporangiophores originating from rhizoids, at first straight, simple, 78-90 µm high (rhizoid excluded), 4.6-6.3 µm wide at the narrowest point near the base, enlarging gradually upward to 10-15 µm wide near the fertile vesicle, bent at this region, then narrowing down to 5.0-6.3 µm wide just below the fertile head, usually single, attached to the host hyphae by stout, dichotomously branching rhizoids. Fertile heads oval to subglobose, 18.8-25.0 µm high by 15-23.8 µm wide, bearing over 40 unbranched merosporangia on its upper hemisphere. Merosporangia cylindrical, slightly curved, each mature merosporangium containing four spores. Spores ellipsoidal, 4.5-7.5 × 2.2-2.7 µm, with minute spines on the wall of the spores. Head collapsed after the spores released. Conspicuous warts left on the upper surface of the head after detachment of the merosporangia. At maturity, spores held in a brown liquid droplet on the top of the sporangiophores. Zygospores not observed.

 Note: The distinguishing character of this species is the bending sporangiophore which enlarging at the bending portion. The similar allied species is S. reflexa, however, the latter without enlarging portion on the sporangiophore and having smaller spores.
