A fungal palynomorph corresponding to the fossil-species Lirasporis intergranifer R. Potonié & S.C.D. Sah, from the Middle Miocene lignite mine in Tomisławice (central Poland), is considered as the new combination Cancellidium intergraniferum (R. Potonié & S.C.D. Sah) G. Worobiec & E. Worobiec, comb. nov. The fossil-genus Lirasporis is treated as a synonym of the modern genus Cancellidium Tubaki. Cancellidium intergraniferum from the Miocene of Poland represents the first fossil record of Cancellidium outside Asia, the first record of this genus from Europe, and the northernmost known fossil occurrence of Cancellidium. Living representatives of Cancellidium seem to prefer warm and humid climates and, being aero-aquatic hyphomycetes, are usually associated with decaying woody remains in aquatic environments. A similar ecology is suggested for the fossil C. intergraniferum, which could be a reliable fungal non-pollen palynomorph proxy for palaeoclimatic and palaeoenvironmental reconstructions.
