Mushroom ID Help???

[Spyd]

Anyone know what type of mushrooms these are? I picked them up as a random frag. I just thought the colours and shape were pretty crazy. Orange, yellow, greens, blues... Pretty wild. I am more of an SPS and LPS guy but the colours in this frag were crazy and I thought it would make a good addition on a separate rock in my LPS tank.

Rhodactis indosinensis.
I suggest placing is a separate rubble away from the SPS.
Here's mine.

Thanks for the fast ID! Are these safe around LPS or will they cause issues? I was going to keep them on a separate rock but I know they can pack up and drift away.

Don't mean to hijack, but any idea what these mushrooms are?

They can potentially sting LPS. IME, they can sting discosoma and ricordea but they lose to bulls eye rhodactis. As to drifting away, I can see that happening if they are too crowded in one area that there is no more space for them to establish their foot. SOme of mine grew on the substrate and gets blown away with strong current (they have larger pieces of sand/crush coral in their feet).
Spork, the name is at the the top of the picture.

I was not asking about the mushrooms in that pic but the ones in the link which I posted under the text here: http://www.reefcentral.com/forums/showthread.php?t=2379316

The coral ID subsection seems to be dead, so here's the pictures of the mushrooms in question:

Oh, sorry. Those are one variety of discosoma.

Awesome, thank you!
I couldn't find any for sale that looked like it coloration wise and was worried it was some type of invasive species. I got it for free on my live rock and left them alone for the most part but am starting to look into keeping more types of corals and didn't want any issues.

You might want to contain them now before they get out of control. Discosomas tend to reproduce faster than most corallimorphs.

I've had them since I started my tank about 10 months ago and they've yet to spread really. Grow, definitely, but not spread. Could this be due to them getting too much light? I was planning on getting some red and/or orange discosomas to complement these guys, bad idea? Or should I just separate the rocks they are on to an isolated area?
