Hertfordshire and Middlesex are full of fungi if you know where to look, and now is the best time to get out and investigate. Find out where to find them in our reserves.

Please do not pick fungi in our nature reserves; they are valuable to wildlife and can be deadly when misidentified and eaten.

Fungi are natural ‘recyclers’: by feeding on dead organic matter, they release nutrients back into the environment. They also support plant life on poor soils by aiding nutrient absorption through plant roots. This role is vital in the food chain of many different habitats – without fungi, the natural world could not function.

Fungi fun facts

  • Before trees, Earth was home to fungi that grew 26 feet tall.
  • Estimates of the world’s number of fungal species run into the millions, outnumbering all other known living organisms put together - in the UK, there are over 4,000 larger fungi species.
  • Orchids cannot germinate without the help of fungi.
  • Mushrooms can release up to 2.7 billion spores a day.
  • It is possible for some mushroom spores to be dormant for a hundred years and then grow successfully into mushrooms.
  • A fungus known as the honey fungus is the largest living organism on the planet. It is believed to be about 2,400 years old and covers over 2,000 acres.
