The paper considers a new species of gleicheniacean fern Tumidopteris astra Naugolnykh sp. nov. from the Lower Permian (Kungurian) and the Middle Permian (Roadian) deposits of the Pechora coal-basin, Russia. The new species is characterized both by macromorphology of the fertile and sterile pinnules and micromorphology of the sori and sporangia. Morphology of the most closely related leptosporangiate ferns is discussed.
