For THOSE kind of mushrooms, you need a pressure cooker, mason jars, vermiculite, brown rice flour, and a way to have really strict temperature control. And a couple months to kill. Never grew them myself, but I've known people who knew people.
For standard button mushrooms like you buy at any grocery store, those are pretty easy, and there are kits online. The trouble is flies, more specifically, the maggots of fungus flies. Commercial mushroom houses use a variety of high-bore pesticides for them, and Organic mushroom farmers use a number of other techniques including beneficial nematodes. Not sure how they recommend home-growers deal with it.
Now, shiitake mushrooms are pretty easy, you grow them in logs. You can buy them pre-inoculated, but I don't know many people who have had much luck with those. I do know people who eventually got rid of some of their shiitake logs that they inoculated themselves because they were getting sick of mushrooms. There are lots of sources online for where to get the inoculant and how to apply it.
