The paper provides in situ records of eight species of spore genera Punctatosporites, Laevigatosporites, Latosporites, Torispora, Cyclogranisporites and Thymospora macerated from fertile plant specimens of genera Asterotheca (A. sp. A and B), Cyathocarpus (C. arborea, C. aff. arborea and Cyathocarpus hemiteloides) and Acitheca (A. ambigua) which come from the Bolsovian to Stephanian B of the Kladno-Rakovník and Pilsen basins, Czech Republic and Scolecopteris hemiteloides from the Permian (Roetligendes), Döhlener Becken, Germany. It is possible to recognize seven morphological types of in situ spores isolated from Paleozoic marattialean ferns. Most of them produced monolete others trilete spores. Sometimes sporangia contain only one morphological type of the spores, sometimes in situ spores are comparable with more dispersed species of two or even four genera. Palynological grouping of Paleozoic marattialeans is based on in situ spores isolated from 124 parent plant species.
