Help with mushrooms (Rhodactis)

[TheCheeseWizz]

I've had these mushrooms for about two months now. Up until the last few weeks they have been perfect. They were open all day and closed at night. Now several of them have not opened in over a week and their "stomachs" seem to be out constantly. Any idea what is happening and what I can do about it?

Water chemistry or lighting is probably the issue.

Please provide lighting and any water chemistry values you have.

Those are mesenterial filaments you're seeing, often seen with chemistry issues or right after a water change.
