| Description： |
Colonies rapidly growing at 25oC, at first light gray, later gray, and at ten days brown. Turf up to 2.7 cm high. Rhizoids present. Sporangiophores 5-12.5 μm wide, 170-278 μm long, typically with a septum 17-25 μm below the apophysis, simple or 2-6 arranged in a whirl growing from stolon, usually with one branch. Sporangia pyriform, 22.8-30 × 19-26.6 μm, surface smooth, sporangial wall deliquescing at maturity leaving a collar. Colummellae hemispherical, 15-22.5 μm in diam, smooth, surmounting a funnel-shaped apophysis, projections usually present on upper surface. Sporangiospores cylindrical, 5 × 2.5-3.75 μm, smooth, rounded at both ends. Zygospores scattered in the aerial mycelium, globose, dark brown, 60-89 × 30-45 μm in diam, suspensors unequal, the larger ones 34 × 20-24 μm, the smaller ones 6-8 × 18-20 μm, finger-like projections growing from larger suspensor and surrounding the zygospore. | |||
