hi, my son's preschool has send home a huge clump of oyster mushrooms to grow at home and had directions to sprinkle water on it every day and store it somewhere dark and warm. about 18 hours ago, I put it in the cupboard and this morning when i checked on it, it had grown hairy spikes from the undersides of the caps that look like spider legs. I've read all about mycillia but I haven't seen anything about it growing from the caps. It really does look like dust caught in a cobweb. I will post a picture shortly so you can join in my confusion (hopefully YOU wont be confused!).
