Why are my mushrooms now funnel shaped?

I think you pretty much nailed this one.
Shrooms where getting nutrients from food. He stop feeding and they are cupping using energy from light.
I've been flirting with low phosphates in a new tank transfer. Even bottomed out once or twice. Some of my shrooms response where to immediately cup as soon as they smelt chun in the water because they where hungry and ulns wasn't providing enough.
I do think alk is concern. Randy made pretty good point to me that yes my ahroomz aren't using cal and alk as much but all my shelled critters and coraline are. So I quit arguing haha
Regular feeding will most likely fix this for sure.

Just mixing up some right now

After a second thought, and mind you I have no experience here, but if they do the cup only when you feed, I’m inclined to believe it is to direct food to their mouth. Laying out flat would be the best way for them to absorb light energy. Cupping should effectively angle the surface away from the light, decreasing the amount of energy being absorbed. Much the way a solar panel works. That leads me to conclude that the cupping posture would not be a response to too little light , is possibly a response to too much light, or simply a method of directing food into their mouth.

Shrooms usually have very obvious responses to too much light. generally they curl up and shrink. Some types, like the discosomas, also develop oxide radicals that resemble white "bubble" growths

Interesting. Forget the par meter.

Exactly what my mushrooms need! If only I had an extra $500 to spend
