Shrunkin Mushrooms???

K so I have some mushrooms that I added to my tank about 2 weeks ago...When I put them in the tank they were wide open but now they always look shrunkin and unhealthy. Does anyone know why or have any suggestions? This is What they looked like when I first got them...

Give us the run down on your equipment,lights,and parameters.

You may have too much flow on them. Not allowing them to fully open as they had.

What yote said. and
What else is in the tank?
