A rare “bearded tooth” fungus which gets its name from its white and hairy appearance has been discovered at a site in Surrey, England, according to scientists.

The fungus, which is also known as “lion’s mane”, “monkey head” and “tree hedgehog”, is virtually confined to old deciduous woodlands in southeast and southwest England, where it grows on tree trunks.

The fungus, which has been discovered near Pirbright in Surrey, is considered to be rare in England, Surrey Wildlife Trust said.

It is used in Chinese medicine to treat digestive upsets and stimulate the immune system, and research is under way into using it to treat digestive tract cancers.

It is a culinary delicacy in the US, and is cultivated on “artificial logs” for cooking.

Ray Tantram, a volunteer for Surrey Wildlife Trust and a fungi expert, said: “It is excellent to have a new record for Surrey of this rare and beautiful species.”

She urged people to help conserve the rare fungus, adding: “Always just look and admire, please do not pick or destroy such valuable additions to Surrey’s biodiversity.”
