Personally I would suggest regional guides. There are thousands of mushroom species so it’s almost an impossible task to make anything that’s both comprehensive and useful. Mushrooms Demystified by David Arora is probably the closest you’d find to being up to the task - it covers about 2000 different mushrooms - though it’s a little old, doesn’t have color pictures, and isn’t really for identifying. I think the purpose was mainly to provide deeper scientific information when you already have a good idea of how to identify and navigate wild mushrooms. It’s also way too large to be a field guide.
Otherwise I’d suggest the National Audubon Society’s mushroom field guide. It covers a good few hundred species and is actually meant for identification. But like all the other guides they publish its organization could use some work. But I really like the regional field guides published by Timber Press. They have lots of information, are useful for identification, and most importantly are actually good field guides.
