Ok, check out this weirdo. I mean the mushroom. If you look at it just right, it looks like Godzilla stomping his leg down. ;)
Laetiporus sulphureus, grown on sterilized substrate, fruiting from inside the sealed bag.
The bipedally-shaped growth is due to bacterial exposure in the air. This was grown in open air in an unfinished basement. I moved this bag and a couple of others like it into my fruiting chamber, to give them a nicer spot to develop more fully.
