I’m happy to suggest some books too, and several of the books that I have are organized by macroscopic characteristics and not families (the more technical books that contain detailed keys tend to be more family-organized.) But I just didn’t list them all since mushroom books can be pretty regional and OP was asking for online sources.
For the east, a great one that’s set up like this is Mushrooms of the Northeast (Walt Sturgeon is one of the authors)
