Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. W. Merriam 1974 | This Disphyllum has corallites of large diameter and multiple columns of predominantly small dissepiments. The tabulae are mostly wide and fairly straight; some specimens are complete and some have peripheral tabellae and a tendency for peripheral depression of tabulae. The septa are slightly thickened in the dissepimentarium; some have weak zigzag carinae. |
