A new lycopod cone, Sporangiostrobus ohioensis sp. nov., is described from the Pennsylvanian of Ohio, U.S.A. It contains megaspores similar to Superbisporites superbus (Bartlett) Potonie and Kremp, and microspores agreeing with Densosporites solans Balme. The genus Densosporites Berry sensu Potonie and Kremp is now known to represent at least two distinct groups of lycopods, and this offers a basis for a natural subdivision of the genus. An emended diagnosis of Sporangiostrobus is given.
