Mushroom ID (in order to help with care)

[NTP66]

Long story short, I tried adding a few frags of various types of coral to my FOWLR to see what my fish would leave alone. The zoas, colt, and acan were gone in days, but everything leaves the mushroom alone - which is nice, because I've seen some great looking/colored mushrooms that I'd like to add later on.

That being said, I'd like an ID on this mushroom. The owner of the LFS I got it from wasn't there at the time, and the woman there wasn't entirely sure. Once I get a positive ID, I can narrow down the care for it. I just added new LEDs (BuildMyLED 20,000k XB's, ramping up to 100% for one hour each day), and run MP40s @ 100%, and want to make sure that I don't need to change anything. This mushroom is in the lower third of the tank in indirect current beneath one of the MP40s.



So, any help (ID and care tips) would be greatly appreciated!

I'd say some type of rhodactis. I keep all my Rhodactis in lower light areas under overhangs or on the outer edges of the tank.

Yeah, I thought it was a rhodactis myself, but can't seem to find an exact match. Here's an awful shot of the placement of the mushroom:



I don't have it in the shade, which would really only be on the other side of my tank, but it doesn't seem to be bleaching or anything. Then again, I don't see it stretch out at all like I have in videos of similar mushrooms. I can move it if need be, but would you recommend lowering the intensity of the lights, or just waiting a little longer to see how it does?
