Anybody on here have experience with them? I unintentionally grew a crap load of them by putting a tarp over some spalted maple logs, I pulled the tarp off yesterday to find what looks to be about 10 pounds of them. Have not harvested any as I am only 99% sure and I know the lookalikes are deadly. Tried a spore print overnight and checked this morning, no print yet, (supposed to be white). They are pretty good size up to 3 inches across the cap and growing in huge clumps.

I am kinda scared to eat them. I have tried many first time mushrooms after checking my mushroom bible as there isn't much risk with most but if you eat the wrong one of these there is a 50% mortality.
