Isognomon alatus, the Flat tree oyster, is a species of Isognomon which has not been observed in the UK before, it is included here because it comes from the same geographic areas as other Isognomen species featured here.

The species is also found in the Gulf of Mexico as are other Isognomon species on this website. The specimen was purchased for reference and photography, should the need ever arise to identify the species here in the UK. It might be found on flotsam, wood, marine plastics or fishing floats or traps.
