dc.description.abstract	Abstract: The species diversity of representatives of the genus Permotheca from the Middle Permian localities Kostovaty and Chepanikha of the Kama region is studied. A new species P.? musaformis sp. nov. is described. The species P. sardykensis, P. disparis, and P. vesicasporoides are identified. New data on in situ pollen are obtained. Pollen grains Vesicaspora and Piceapollenites were found in the sporangia of P. disparis; the sporangia of P. vesicasporoides contain solitary Pityosporites pollen grains apart from Vesicaspora pollen grains. A new diagnosis is proposed for the genus Permotheca in the light of new data.
