Abstract
A new bisporangiate lycopsid cone genus Thomasostrobus gen. nov. from the Stephanian strata of the Intra-Sudetic Basin (Czech Republic) is proposed as a new organ genus with mega- and microsporangia arranged in zones. Microspores assigned to the dispersed genus Cadiospora and megaspores comparable with the dispersed species Sublagenicula levis, are described in situ for the first time.
The possible parent plant of Thomasostrobus longus is discussed and an overview of dispersed Cadiospora and Sublagenicula spores is given.
