Any reasons my shrooms make this shape?

For a couple days now during the day when the lights are on, Ive noticed my mushrooms have been making somewhat of a bell shape that Im not used to seeing. Here are some pics. Is there a reason why they are making this shape? (Kind of hard to explain, hopefully the pic tells all).

Mine were doing the same thing and I believe it was because of the flow. I had a PH that was behind my LR that was really coming through strong. I moved the PH and the shroom went back to its normal look.

That may be it, I do have a power filter behind this rock. So I'll move it and see what happens.

I dont think its the flow. For a about a week i had to keep my mushrooms in a different tank (my aquapod stand collapsed and the tank broke) The tank i threw them in had no PH and i was noticing this shape every once and a while. I figured it was because of the low lighting on the tank, but i have no clue really.

I think it could be flow but really have no idea. Is this say Good or bad for it?
