S t r a t i g r a p h y: Peruc-Korycany Formation, Cenomanian, Upper Cretaceous.

D e s c r i p t i o n. The single specimen no. GBA_10 (Pl. 8, Fig. 12a, b) represents a microsporangiate (pollen) cone of conical shape (20× 6 mm). The microsporangiate cone is widest at its lower part, narrowing to the upper part and obtusely terminated. The cone is borne on a 20 mm long and 3 mm wide peduncle. This microsporangiate cone consists of numerous helically arranged microsporophylls borne on one central axis. Microsporophylls are irregularly hexagonal in shape, 0.7×0.7 mm in size.
D i s c u s s i o n. The pollen cone Masculostrobus sp. 2 differs from the pollen cone Masculostrobus sp. 1 in having a conical shape and smaller microsporophylls. It differs from the genus Conago in having small densely arranged hexagonal microsporophylls.
