 Description: Turf growing on SMA at 25°C at first white, 2 weeks later becoming gray and after 1 month brownish black. Stolons at first white later brown. Rhizoids well developed. Sporangiophores erect without branch, at first white later becoming brown, 1-5 as a group originating from the opposite side of rhizoids, 900-2700 μm in length, 22-32 μm in diam, at first white, black when mature. Sporangia globose, 173-235 μm in diam, sporangial wall smooth, easily dissolved when mature. Columellae globose, smooth, 153-163 μm in diam. After spores dispersed, columellae mostly depressed to become hemi-globose. Sporangiospores globose-ellipsoidal- angular , with many striations running over the surface mainly parallel to the long axis, gray, 7.5-9.6 × 4.3-7.5 μm. Heterothallic. Zygospores observed, black, globose-subglobose, 116.0-185.0 μm in diam, wall-thick, warted.

 Note: The author identified these isolates followed the key in Schipper’s monograph. These isolates have common features of Rhizopus stolonifer, such as (a). sporangiophores often more than 1 mm in length; (b). rhizoids with secondary branching; (c). sporangia often over 100 μm in diam; (d). no growth at 36 oC; (e). heterothallic.
