Cunninghamella echinulata (Thaxt.) Thaxt., Rhodora 5: 98. 1903.

 Description: Colonies at 25℃ spreading rapidly, white to pale buff on maturity, powdery in appearance, growing at 40℃; sporangiophores erect, with solitary, opposite, verticillate, pseudoverticillate or irregular branches, the laterals sometimes showing secondary branching; terminal vesicles spherical to subglobose, 24.8-44 μm in width, average 34.8 μm, lateral vesicles smaller than terminal vesicles but no conspicuous difference in shape, 18-29.6 μm in width, average 23.5 μm; sporangiola hyaline, predominantly spherical, sometimes subglobose to broadly ellipsoidal, 9.6-20.5 × 9.4-20.4 μm in diameter, average 13.5 × 13.4 μm, usually thickly beset with spines up to 4 μm in length, sometimes smooth; chlamydospores subglobose to ellipsoidal in shape, average 26.8 × 18.2 μm in diameter; zygosporangia spherical to ellipsoidal, 26.8-46 × 25.6-38 μm in diameter, average 36.9 × 32.7 μm, reddish brown, warted; suspensors hyaline, smooth, 10.8-42.4 × 8.8-36.6 μm in size, average 20.1 × 16.2 μm. Heterothallic.

 Note: Cutter (1946) has indicated that there was no verticillate branched sporangiophore in this species. But in the cultures studied here, the verticillate form could be discerned. Samson (1969) and Baijal & Mehrotra (1980) also have described this branching pattern. This species can be distinguished from other species of Cunninghamella by its powdery appearance and pseudoverticillately branched sporangiophores.
