I have quite a few corals and for the life of me I can't remember what this is now...have had 60% of them in a frag tank setup at a buddy's house for 3 months in preparation of my large system getting set up but have had a few set backs setting it up...long story short I went and picked up about 15% of them and much has grown out by now...I don't remember this one ...looks like a mushroom but has feeder arms

sinularia dura is what a few members have said...looks to be a dead ringer

Yep. That's it.

I agree. Here is a link to an article by Bob Goemans, who is usually quite good. I've met and interviewed him. He suggests using a good quality activated carbon to combate "coral warfare."
