| One of these species, a ramose form with thin branches, was not found in the coral reef zone lower in the section. |

| As with ramose colonies, frondose forms were weakened when Sanctum laurentiensis mined out large chambers. |
|
| In the root mantle, the borings are somewhat ramose and wind around the roots in the ground tissue. |
