Field Guide to Common Macrofungi in Eastern Forests and Their Ecosystem Functions
USDA Forest Service, Northern Research Station
The rare PUBLIC-DOMAIN mushroom guide with quality color photos (incl. deadly Amanita and Galerina species). Deliberately ecology-focused rather than an edibility guide — which fits the safety-first stance: show what grows, never promise edibility.
Editor's notes
Covers Midwest/Northeast forest types only. Do NOT editorially convert it into an edibility guide; frame mushrooms as identify-for-interest, eat only with local expert confirmation.
