Although it had stopped developing and was turning brownish my guess is that it had stopped developing due to a recent dry spell here. I picked it and tore it apart- the spines are attached to a cluster of tightly packed branches and range in length from 5mm or less to as much as 20mm in length. My references indicate that H. coralloides spines are less than 10mm long and H. americanum spines 20mm to 40mm in length- on that basis I call it an immature H. americanum.
