Log every find, map the spot
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
A journal for foragers. Pin every mushroom you find, keep the weather and the day it fruited, and know when the spot is worth walking back to.
Mycelia is a field journal for mushroom foragers. Photograph a find, name it yourself, and pin it to a private map that fills in over the seasons.
It does not identify mushrooms for you. That's the point.
FIND
• Snap a photo in the field and pin it to the map with GPS
• Name the find yourself — you're the one identifying it
• Location, weather, and days since last rain attach automatically
• Record quantity, habitat, and your own observations
• Your spots stay private by default
EDIBILITY IS YOURS
• Give each find your own label — edible, unsure, toxic, or leave it blank
• Mycelia never sets one for you and never checks one
• Reference material is shown as what field guides say, attributed rather than asserted
• Look-alike warnings name the dangerous confusions for a species and the one feature that separates them
• Your local poison-control number, one tap away on anything you've flagged toxic
REMEMBER
• Finds collect into a dated timeline, a by-species view, and a map of your spots
• Return predictions estimate when each patch is likely to fruit again
• Open directions straight back to a spot you logged last season
• Send any find to iNaturalist when you want a human expert to look at it
OPTIONAL: AI SUGGESTIONS
• Off by default. Turn them on in Settings if you want a second opinion.
• Suggestions offer species names to go and check — never an edibility verdict
• Offered only after you've written up a find yourself, never before
• With the setting off, no photo ever leaves your phone
PRIVATE BY DEFAULT
• Your spots are yours. Nothing is shared unless you choose to share it.
• Sign in with Apple, Google, or email to back up and sync across devices — or skip the account entirely and keep everything on your phone
• Share individual finds with the community as cards, while notes and quantities stay private
• Delete your account and all its data from inside the app at any time
SAFETY
Mycelia is a notebook, not an authority. It does not identify mushrooms and it will never tell you that something is safe to eat. Mushroom misidentification can be fatal — always confirm with a printed field guide and an experienced forager before eating any wild mushroom.
Ratings & Reviews
Mycelia has changed its mind about one thing: who decides what a mushroom is.
It's you. The app is a notebook, not an expert — and this release makes that true everywhere, not just in the small print.
YOU NAME THE FIND
• Photograph a mushroom and go straight to your own field note. Nothing guesses at it first.
• The green button is now "Pin it" — it opens the camera and pins the spot, and that's all it claims to do.
• Home opens on your own foraging map once you've logged a few spots.
EDIBILITY IS YOURS TO SET
• Every find carries the label you gave it — edible, unsure, toxic, or nothing at all, which is the default.
• Mycelia never fills it in and never checks it.
• Where we hold reference material, it's shown as "what field guides say", clearly marked as theirs.
• Look-alike warnings are unchanged and still lead: they're the part that protects you.
AI SUGGESTIONS ARE NOW OFF BY DEFAULT
• Turn them on in Settings if you want a second opinion. Left off, no photo ever leaves your phone.
• When on, suggestions are offered after you've written up a find — never before.
• They return species names to go and check. No edibility verdict, and no confidence percentage dressed up as certainty.
SAFETY
• The poison-control number now matches your country instead of always showing a US line, and you can set your own.
• A one-time acknowledgement at first launch, so nobody meets this app without knowing what it won't do.
Mycelia does not identify mushrooms and will never tell you something is safe to eat. Misidentification can be fatal — always confirm with a printed field guide and someone who knows the species where you forage.
