Excited scientists believe mushrooms hold the secret to eradicating disease.
They want us to treat the discovery of new fungi as seriously as hunting for extraterrestrials.
Researchers say there are two million species waiting to be identified around the world – and they are a new frontier for discovery.
They are hopeful they could identify 50,000 new types a year and reckon they could help us cure most diseases.
Professor Alexandre Antonelli, director of science at Kew Gardens in London, said: “Fungi are sustaining our life, our vegetation, they are absolutely crucial for every single animal species.
“Now we have DNA analysis, we are trying to push the frontiers. It’s quite similar to exploring the outer universe.”
