Here is our guide to 10 of the most common wild mushroom species found in Britain, each with a few key details regarding where they grow, characteristics and whether they are edible or poisonous.

Mushroom picking and safety

If you are unsure whether a wild mushroom is safe to eat or not, seek advice from an expert. Eating a poisonous mushroom can be fatal – or at least make you feel very unwell, so don’t risk it. There are many foraging courses you can join where you can be guided by an expert.

How to forage responsibly

Always be sure you can positively identify any plant before you pick it, and never eat any plant you are unsure of. When foraging, ensure you leave plenty for wildlife.

Here are a couple of key foraging guidelines:

  • Seek permission before foraging. In certain areas, plant species will be protected so it is important to do some research and check with the landowner before you start gathering.
  • Only pick from areas that have a plentiful supply. Look for areas where you can find food in abundance and then only collect a small amount for personal use. Never completely strip an area as this could damage the species and deny another forager the chance to collect.
  • Leave enough for wildlife and avoid damaging habitats.Many animals rely on plants for survival, so never take more than you plan to eat as this could also deny wildlife from a valuable food source. Be mindful about wildlife habitats and avoid disturbing or damaging.
  • Never pick protected species or cause permanent damage. Britain’s wild plants are all protected under the Wildlife and Countryside Act (1981), which makes it illegal to dig up or remove a plant. Check the law before you forage or if in doubt, why not take part in a foraging class with an expert and learn the basics.
