Bought this for $5 so I dont really care either way what it is.

I think it is a mushroom but I am not too sure. Is about the size of a dime.
It almost looks like a small plate coral too me( I wish!!) but think its a mushroom what do you guys think?

just from the picture, it looks like a kind of rhodactis mushroom.... But a better pic could help.
