Please help ID this mushroom

I have this mushroom that has multiplied all over my tank. I'm thinking of trading it but don't know what to call it or how much it might go for at a LFS. Any help would be greatly appreciated. Thanks.

I've seen that kind of mushroom listed as Rhodactis sp. and Discosoma carlgreni. I've even seen pictures of them captioned as elephant ear mushrooms, but mine maxed out at about 5 inches fully expanded, no where near as large as my elephant ear mushroom. I bought one for $5 once, but it was in a loose mushroom tank where everything was just $5. Ive also seen medium sized ones for $30 and full sized ones for $60. I think they are nicer than the non-forked tentacled hairy mushrooms that are more common in the hobby.

Here's one for $60, but I wouldn't expect anywhere near that trying to sell it to a lfs, on eBay, etc.
