The festival also focuses on fungi, specifically with sculptor Tom Hare's "Fungi Fairy Ring," a series of sculptures that represent the seven types of edible fungi.

"With the first official Red List for fungi in Britain recently published, it is a momentous time for the conservation of fungi in the U.K.," Dr. Bryn Dentiger, the director of Kew's Fungarium, said in a news release. " is an opportunity to raise awareness about their importance to the health of the planet, their role as the hidden benefactors of most edible plants."
