If you pull them up before the 'pop' open into Christmas tree shape, then you should burn them - they still contain spores apparently. Once they've popped open, they've thrown the spores around and they should be safe to compost, or bash them, add to water for a few days then use the water on your plants? They supposedly contain good stuff! I have even heard of them being used in some kind of tonic for hair/nail strength, but I've never tried it!

“Of course it is happening inside your head, Harry, but why on earth should that mean that it is not real?”
