But even the hungriest of mushroom fans might find this monster mushroom, recently discovered in Yunnan, a little hard to swallow.

Fungi, including mushrooms, are neither plants nor animals and instead form their own group of living organisms that generally reproduce by spores and contain nuclei with chromosomes. Perhaps surprisingly due to their plantlike appearance, fungi are more closely related to animals than to plants.
China's mushroom industry is a multimillion-dollar operation, with sales equivalent to $44 million in 2005, according to The Diplomat. And some of the finest and costliest specimens, such as the rare Tricholoma matsutake mushroom — highly prized as a delicacy in Japan — come from Yunnan.
