it looks okay. Mushrooms are funny every once in a while mine will do that for a day or two. how long has it been like that and how long have you had it, also it does hurt to move it around a bit to find the place where it expands the best.
ive had it for 2 weeks and it will do it for a a couple days like you said and then expand. I've been moving it around but it doesn't know what it wants...lol
