Mushroom ID, please!

[jamie907]

I got these at the LFS for $6.99 a piece, and I don't know what kind of mushrooms they are. Also, what's a good way to make them spread?
Thanks for the help. :jumping:
Oh, and sorry my clown decided to get in the way of the picture. She's such a ham.

Are they the same color and size as they were in the store? Ours change to a different color at night and if they get stressed (like when I or a crab touch them). Shrooms usually are pretty prolithic.

Yeah, they pretty much stayed the same. One of them kind of crumped around my finger when I tried to move it. I just want to know what kind of shrooms they are.
