Occurrence of spores from an isoetalean lycopsid of the Polysporia-type in the Late Devonian of Ohio, USA
Original language description
Thousands of dispersed megaspores of the Valvisisporites auritus-type, some isolated megasporangia still containing them and dispersed microspores of the Endosporites globiformis-type have been found occurring in close association in the Late Devonian (Famennian) of Ohio, USA. Until now, these spores have only been found in the Carboniferous, where they have been shown to have been produced by isoetalean lycopsids assigned to the plant genus Chaloneria and the morphogenus Polysporia. The present work describes, using LM, SEM and TEM, megaspores of V. auritus-type, megasporangia containing these megaspores, and microspores of E. globiformis-type.
