The National Audubon Society’s Field Guide to Mushrooms was the first guide for many, and a solid go-to.

Peterson’s Guide has fantastic illustrations. I could spend hours browsing these pages. Excellent for beginners.

Mushrooms of the Redwood Coast focuses on species sourced in Northern California, but there is some general PNW overlap. Excellent images, easy to use.

Edible Wild Mushrooms of North America gives special attention to edible species of mushrooms, not just the eye-catchers. If that strikes your fancy.

All That the Rain Promises and More, fantastic cover aside, is a well-respected guide for the comfortable forager. It’s always good practice to double-check.
