Frustules of Campylodiscus possess a complicated three-dimensional structure which is often termed a distinctive "saddle shape". Like the other genera within the family Surirellaceae, the raphe system is raised onto a keel and positioned along the entire valve margin. Cells possess a single chloroplast, with two lobed margins.
Cells grow singly in epipelic habitats of freshwaters, brackish waters and marine waters.
