Read full description

Explore possible mushroom matches from photos, compare their features, and save your discoveries. PHOTO IDENTIFICATION Take a photo or import one from your library. Add different views of the cap, stem and underside to explore possible species matches. Results are suggestions, not confirmed identifications. A SPECIES LIBRARY TO EXPLORE Search by common or scientific name. Browse reference photographs, taxonomy and available species information. Detail and photo availability vary by record. LOOK CLOSER AT LOOKALIKES Explore visible characteristics and similar species when information is available. A photo alone cannot establish whether a mushroom is safe to eat. ASK AN AI GUIDE Ask questions about fungal features, habitat and lookalikes. The guide is AI, not a human expert, and its answers may be incomplete or incorrect. YOUR PERSONAL COLLECTION Save species and revisit previous scans, photographs and reports on this device. Build a field book of your discoveries. Free access includes 1 photo identification and 1 AI guide question per day, up to 3 distinct library searches per day, and space for 1 saved mushroom in your collection. Optional Premium subscriptions expand access and include AI name search beyond the library and additional learning content. Available plans, prices and renewal terms are shown in the app. Subscriptions renew automatically unless canceled. IMPORTANT SAFETY INFORMATION Never eat a mushroom based on an app result or AI answer. Confirm identification and edibility with a qualified local mushroom expert. This app is for learning, not medical advice or a safety assessment. Online identification, AI responses and new library data require an internet connection.
