Haha myth busters cool!
Anyways, the cells of mushrooms are totipotent, which is a biological term meaning that every single cell of the organism has the ability to become a clone of the parent organism. Plants have this ability too this is why you can create invitro carrots etc. Stem cells also fall into this category and is why they are being used in stem cell research because they might be able to be targetted to become certain organs etcetc.
I'm not exactly sure if this would work on the musrooms in the blender, but it definitely has the potential to work because of the totipotency. Remeber the blender will destroy and break apart some of the cells, but if even a few cells survive the beating, they could very well have the potential to grow a clone of the parent mushroom. Not every single cell of the surviving cells will become a daughter mushroom, (think: Dolly the cloned sheep was 1 out of 277 tries of sheep mammary gland cells that worked), but it really could work. The best thing would be to try this yourself (maybe in a small isolated tank in case it does and you overrun the tank with shrooms), and let everyone know what happens. What's sacrificing ONE mushroom if it doesn't work anyways?
