Male Fern is classed as poisonous in the Forage field guide. This page helps you identify it and tell it apart from similar species. It is not a foraging guide. When in doubt, have a find identified by an expert.
If you suspect poisoning, call your local poison control center right away. If someone has trouble breathing, has a seizure or is unconscious, call emergency services. Don't wait for symptoms: with some poisonings they only start hours later. Keep any leftovers of the find, they help identify it.

Forage helps you discover and identify wild plants, but identification is never 100% certain. Many edible plants have toxic lookalikes. Never eat anything you find based only on what this app tells you. Always confirm with a field guide, an experienced forager or a local expert. The season score tells you where to look, too: it’s not a guarantee. Mind conservation law and property rights as well.
