Graticula, formerly incorrectly named Craticula,^[1] is a genus of Palaeozoic coralline alga.^[2] They form the framework of reef rocks in the Silurian of Gotland, from the Högklint, Slite and Halla groups.^[3]

The Graticulaceae closely resemble the Cretaceous Solenoporaceae, and are only really differentiated by their stratigraphic position.^[2]

Graticula mineralized with calcite.^[4]^{[clarification needed]}
