I got some new mushrooms and I've noticed that most are opening up nicely during the day, but one of them has been closed for a few days. Today I saw what might be the reason. There were two tentacles coming out of the rock he's attached to. The tentacles are clear/white colored and about 1" long and very thin. Any ideas? I hit the closed mushroom with a blast of water from a turkey baster and noticed he has several curly white things on him. It looks like really skinny spaghetti that's curled up in spirals. These look similar to the tentacles that are coming out from the rock. Does anyone have any ideas of what this could be? Thanks.
