Yes, the Mushroom King is a book, but it an unfinished book. I haven't had time to finish putting it together for well over a year. It's something that's bugged the crap out of me but hopefully one day... There is always the possibility of me emailing you the manuscript for it. (as long as you don't steal it and make a bajillion dollars, that is) I need more people to read it and give their two cents!
