1. Observe in place
Follow the rules of the place you are visiting. The National Park Service encourages photographing interesting mushrooms and leaving them for others to enjoy.
2. Record one specimen from different angles
In Mycovela, use up to three photos of the same specimen. Where visible without disturbing it, compare side, top and underside views. Do not mix photos of different mushrooms in one attempt.
3. Compare the references carefully
Read the possible matches, visible features, habitat notes and look-alikes. Missing features and similar-looking species can leave important uncertainty.
4. Learn with a local expert
Use regional references and a qualified local expert to continue learning. A photo or app result does not establish that a mushroom is safe to eat.
