Cunninghamella echinulata

The spores in Cunninghamella originate synchronously from a spherical vesicle at the tip of the sporophore or one of its branches.   At maturity each spore is covered with long, sharp, needle-like spines of calcium oxalate.  In this micrograph the spores on the terminal vesicle have matured and dispersed.
