The Spore project - have you heard of it where you live? I stumbled across this awhile ago and can only imagine what it must look like to see all of these paperbag mushrooms on display.
If you click on the link you will find more photos and also directions to make your own mushroom. I was going to have a go but the only suitable paper bag is a huge one. Must keep the paperbag that we buy our mushrooms in, next time. I should remember that one - I think.
