Racekiela ryderi is a species of freshwater sponge in the family Spongillidae.

[1] It was first described by Edward Potts in 1882.

[2] It was collected on Sable Island in 1899 by John Macoun, a biologist with the Geological Survey of Canada, and given the name Heteromeyenia macouni by A.H. Mackay in 1900.

[3] It was originally assumed to be endemic to Sable Island but is now considered to be the same species as Racekiela ryderi, which is more broadly distributed.
