Discussion
Buxbaumia piperi has occasionally been confused with this species, but the sporangium shape (narrowly ovate to cylindric) and the shorter, often arcuate seta separate B. minakatae; B. piperi has a longer, straight seta and ovate sporangium. A report of B. indusiata (A. J. Grout 1928–1940, vol. 1) was based on misidentifications of eastern North American material.
