Nuclear weapons will do the trick.

They are pretty tenacious, even if you scrape them off sometimes all it takes is a small piece to regrow. I think Anthony Calfo said that someone put a mushroom in a blender, and got some mushrooms to grow... But I think if you use a screwdriver or something to gouge out the surface of the rock where the mushroom was growing you should be OK.
