Superman mushroom guts?

Anyone know what's going on with this shroom? It's been like this since I got it. Is is splitting? It seems to be happy.

Those are it's guts and to be honest it looks deflated and unhappy to me. If you've only had it a couple days I'd just be patient. If it's been like that a 5-6 days I'd try moving it someplace where the lighting is similar to whaht it grew under.
