Unidentified Horn Coral

This horn coral was found in Clark County, Indiana. It is of the Devonian Period and I am still try to figure out its identification.

UPDATE (2021): This could be a Bordenia knappi (Hall, 1882). Found in the Speed Limestone of Clark County, Indiana USA.

    Could it be related to Acathophyllum?

    I am not sure. Do you have any references that describe the Acathophyllum?
