In the rich macroflora from the Stephanian of the Blanzy-Montceau basin (Massif Central, France), several very large, heterosporous lycopod cones have been found whose microspores and megaspores correspond, respectively, to the well known sporne dispersae genera Endosporites Wilson & Сое and Valvisisporites (Ibrahim) Potonié & Kremp. The structure of these cones and the type of their spores, both micro-and megaspores, led us to assign these new fructifications to the genus Polysporia newberry and to create the new species, P. doubingeri. The combination Endosporites-Valvisisporites also proved to characterize other lycopods among which Chaloneria Pigg & Rothwell from the Pennsylvanian of North America which has been classified into the Chal...
