I recently grabbed a number of mushrooms from my lfs, and some of them are acting strange! My superman mushrooms and some of my green ones have been acting normally and opening up fully ever since i put them in the tank. However, my two knobby mushrooms (possibly rhodactis mushrooms?) have seemed to close up once they placed their foot. They have been fully open for about a week and a half, and then all of a sudden just started closing up pretty tight for some reason. is this normal? Ill post some pics once my lights come on, I can't get my phone to take good pics under my moonlights! Also, one of them is doing it more than the other. Thanks for your help!
