Unknown Devonian Horn Coral

I am not sure what this horn coral is called. This one has 43 septa and must have been deformed into an elliptical shape. This horn coral was found in Louisville, Kentucky in maybe the Jeffersonville and Louisville Limestone.

The outside has beekite patterns.

Genus Heliophyllum Devonian Horn Coral

Here are some pictures of a Heliophyllum horn coral of unknown species from the Devonian period. I make the identification as Heliophyllum because it was found in Louisville, Kentucky in the Jeffersonville Limestone and the septa have small beads or teeth along the line.

The images go from a close up of the lines to further out of the coral fragment.
