sparsiflora has been found to host discrete populations of Acaulospora AM fungi (AMF (ecology)) on serpentine soil, Glomus on non-serpentine soil types.
In 1939, Edwin John Butler described a Glomus aggregatum-like organism, but a name was not assigned to this species until 1943, when C.O. Rosendahl further elaborated the specifics on what he dubbed Rhizophagites butleri Rosendahl.
