Mushroom picking is a low-risk hobby with a small number of high-consequence mistakes. The risk is not spread evenly across species: a handful account for nearly all serious poisonings, and they are all mistaken for common edible ones.
None of the habits below depend on which app you use. They are what makes the app safe to carry.
The rules
- Never eat a mushroom you are not certain about, and treat "probably" as "no".
- Never rely on a photo comparison — from an app, a book or a website — as the final word on edibility.
- Get an in-person check from someone qualified before eating an unfamiliar species. In Norway, mushroom control stations run through the season for exactly this purpose.
- Learn the dangerous species first. Knowing what to avoid is more useful than knowing many edible ones.
- Learn a small number of species properly rather than many superficially.
- Do not rely on folk tests — silver spoons, animals eating it, cooking it thoroughly. None of them work.
Practical habits in the field
- Carry an open basket rather than a plastic bag, so spores drop and the mushrooms do not sweat.
- Keep uncertain finds separate from the ones you are confident about — separate containers, not one basket.
- Lift the whole mushroom including the base when you intend to identify it.
- Note the habitat while you are standing in it; you will not remember it accurately at the kitchen table.
- Tell someone where you are going, and remember that a phone in a forest often has no signal.
If something goes wrong
If you or someone else has eaten a mushroom and feels unwell, contact emergency services or a poison information centre immediately — do not wait to see whether it passes. Some of the most serious poisonings have a symptom-free interval of many hours, and treatment is far more effective when it starts early.
Keep any remaining mushroom, and the photographs you took. Identification of the actual specimen changes the treatment.
How the app fits in
- 1
Use it to look properly
The feature guide is a checklist for examination, not a verdict.
- 2
Photograph everything you pick
If a question arises later, the photos are what make it answerable.
- 3
Take uncertain finds to a real check
A mushroom control station or an experienced forager, in person.
- 4
Log what you learn
Saved finds with dates and positions build genuine local knowledge over seasons.

Frequently asked questions
Is an app enough to start foraging?
It is a good learning tool and a good field notebook. It is not a substitute for an in-person check before eating anything unfamiliar.
What should I learn first?
The dangerous species in your area, and the common edible species they are confused with. That pairing is the useful unit of knowledge.
