The Pacific Northwest Key Council is dedicated to the creation and publication of field keys to the fungi of the Pacific Northwest. It was initiated in 1974 by Kit Scates of Post Falls, Idaho, and developed with the support and supervision of Dr. Joseph Ammirati and the late Dr. Daniel Stuntz, both of the University of Washington. The geographic area covered is southern British Columbia, Washington, Oregon, Idaho, and western Montana.

The Key Council develops, refines, and field tests keys to selected species and genera of mushrooms of the Pacific Northwest. The mushroom characteristics in the keys are based on macroscopic features that can be seen by the naked eye or hand lens. All keys are subject to peer review and editing before publication. Key Council membership, which is by invitation, includes both professional mycologists and amateurs.

The following list consists of those keys that are available online. For PNW Council keys available in paper form, see Keys on paper.
