ABSTRAT: Cunninghamella bainieri Naum.was conisidered to be distinct from C.echinulata (Thaxt.)Thaxt.ex
Blakeslee after a detailed study on the morphology has been made. In mating experiments, however, the two taxa
were found to be to mate and procuce fertile zygospores between each other when (+)and (-)strains were present.C.bainieri is, therefore, reduced to varietal rank as C.echinulata var. verlicillata (Paine) comb. nov. Criteria for separating the two taxa are discussed.R edescriptions and illustrations of both taxa are also provided.
