How to identify paly coral in a pulsing Xenia shipment

Can someone help me identify these palys?

I ordered some pulsing Xenia from an out of state vendor and my shipment arrived yesterday. The packaging was excellent and shipping was fast. There was also a bonus mushroom included as a free gift, which is awesome (last picture). However, one of the Xenia frags also had an extra on it. I didn’t figure out it was palys until after everything had been dipped, rinsed, and added to my observation tank. I’ll plan to separate the palys and Xenia after they’ve all had a week to stabilize in the tank. Thank you to TiA Corals, in Deerpark, NY, for the awesome online experience!
