The bamboo fungus egg is what bamboo fungus looks like when it is a child, which is its embryo. It is called a bamboo fungus egg because the bamboo fungus embryo is round and has a distinct layering when cut, just like the yolk and white of an egg. The embryo is made up of four parts: montmorillon, spores, cap, and outer covering. Mengsun is what we often call bamboo fungus mushroom, which is the unfinished embryo of bamboo fungus, mushroom-like, milky white, with a fresh and tender taste; the outer covering and the cap of the fungus, which is in the form of a milky white translucent net, is also known as the flower of bamboo fungus, which has a crunchy and tasty taste.
