Remark: Some samples were found in the boreholes Kf-1, Kf-6 and Gy-12, from 528.6 m. Spermatites pylophorus Miner 1935 Figs 32-33 Description: Cuticular seed coat obovate to oblong-elliptical in shape, 800-1000 pm long and 300-600 pm wide. The micropyle is reticulated. Remark: This species occurs in big numbers in the borehole Gy-12 in between 543.2 and 513.0 m in the Munieria bearing clay-marl. Spermatites kaptalanfaènsis n.sp. Figs 35-41 Holotype: No BP 2000.1.1, Fig. 35. Type locality: Gyepükaján, borehole No 12, from 528.6 m. Stratigraphical position: yellow marl Ajka Coal Formation, Senonian. Etymology: From the name of the village near the borehole. Diagnosis: The oval-shaped cuticular seed with an extended end. The whole body is covered by reticulated ornament that forms numerous loops. At the extension, the loops somewhat straighten and become wound. Description: The specimen is a cuticular seed 833 pm long and 555 pm wide, with one end elongated into a beak-shaped, 200-250 pm long extension. The whole body appears to have a fiber-like and reticulated, almost ornamented cover with numerous loops. Their size is about 10-15 pm. Between the meshes a net-like structure is observed (Figs 38-39). At the beak the loops (Figs 37, 40-41) become straightened and, upon reaching the end, form a loose spiral (Fig. 36). Remark: The presence of ornament is the main difference between the new species and those known so far. This form is common in certain levels of the Nh1, Kf1, Kf-6, and Gy-2 boreholes.
