Foraging safely

This is the single most important rule in foraging. Never eat anything based on a single identification — not from an app, not from an AI suggestion, not from a single photo match, and not from a single person's say-so.

Before you eat anything, cross-reference your identification against at least two reputable field guides. Ideally, have an experienced forager or mycologist verify it in person. The ForageGB ID Workbench and any AI pre-screen are advisory only — community consensus and AI are starting points, never determinations.

Many of the deadliest species have edible lookalikes. And the symptoms of the most dangerous poisonings — such as those caused by amatoxins — are delayed by hours or even days, by which time irreversible organ damage may already be done.

A confident identification requires checking multiple features of the specimen:

• Habitat and substrate — what it grows on, and where (woodland, grassland, near specific trees)
• The whole specimen — cap shape, colour, and texture; gills or pores; stem structure; the base (bulb, cup, or rhizomorph); any ring or volva
• Spore print colour — cut the cap and place it gill-side down on paper overnight
• Smell — fresh fungal smell, anise, almonds, or other distinctive odours
• Season — when it typically fruits
• Flesh colour changes when cut — oxidation or bruising can be diagnostic

Always use at least two independent field guides to verify every feature. When you are unsure, take clear photos from multiple angles and post them to the ID Workbench for expert community input — but still verify independently before eating.

Consider joining a local fungus group or attending a guided foray. Learning from experienced mycologists in the field is invaluable.

Learn to recognize these species before you forage. You can find detailed write-ups of the Death Cap on the Woodland Trust (opens in a new tab), and of the Destroying Angel, Deadly Webcap, and a wider list of poisonous UK fungi on Wild Food UK (opens in a new tab).

• Never eat on a single identification
• Only eat species you have positively identified and know to be edible
• Never eat wild fungi raw
• Cook thoroughly
• The first time you try an edible species, eat only a small amount and keep a sample in case of adverse reaction
• Eat one new species at a time — never mix new species in the same meal
• Avoid specimens growing on polluted ground, roadsides, or sprayed areas
• Keep all wild fungi away from young children and pets
• If in any doubt, leave it out

If you or someone else may have been poisoned, see our poisoning guide. Call 999 in an emergency.

Forage legally and responsibly. Read our foraging law guide and our code of conduct to understand your rights and responsibilities.
