Anisopteris shuteana Hayes et H.L.Pearson sp. nov., a rare fertile adpression fossil, is described from the Mississippian of Teilia Quarry, Gwaenysgor, North Wales, UK. The new species is based on material from the Margaret Benson Collection and named in honour of Cedric H. Shute who curated the Palaeobotany Collections at the Natural History Museum, London. The account arises from an unpublished typescript by Benson, who considered the specimen to be a fern fructification. A. shuteana is of particular importance because only two fertile fronds of Anisopteris have previously been described. Detailed comparisons are drawn between these two species, Anisopteris fertilis (J.Walton) Hirmer, 1940 and Anisopteris lindseaeformis (Bunbury) Hirmer, 1940 and A. shuteana, which is assigned to the Lyginopteridales.
