Organic mushroom farming and mycoremediation by Trade Cotter. A more layman's version than Paul's books. Also focuses on off grid low tech growing.
Find a wild mushroom book for your area, if there is one for Kansas there
should be one for just about anywhere.
As for growing them, it is better IMO to figure out what substrate you want to use and then figure out what to grow. I can't get organic
straw but have nearly unlimited access to nearly free sawdust (just costs me gas to go get it), so that changes how and what I grow.
