Coral ID please

[Omikayalan]

Can someone please help me identifying this coral? It came as a hitchhiker on a clove polyp frag. The coral encrusted onto the clove polyps and killed them. My guess is it could be erythropodium caribaeorum or maybe sarcothelia, but i am not sure. The base looks like purple melted wax on the rock.
