ABSTRACT: A new species, Syncephatastrum monosporum sp. nov., consisting of three varieties, var. nomosporum. var. cristatum var. nov., is described. All varieties differ from the monotypic species of the fgenus. Syncephalastrum racemosum Cohn ex Schroeter, by possessing only unispored sporagiola(merosporangia) instead of several-spored merosporangia. These are the first reports of monosporous merosporangia in any true Mucorales. Reasons for trferring the new taxa to the genus Syncephalastrum and not erecting a new genus to accommodate them, as well as the defferences among the new taxa themselves, are briefly discussed.
