Puerh History - Pu-erh.Net

„Mushroom shaped tea appeared in 1912. It was invented at that time in order to prevent the tea from going mouldy during the transportation. It was produced in Xia-Guan and Fo-Hai (two cities in south China) with the trademark "Bao-Yan". The production was then stopped in 1966. In 1986, the production was resumed due to the request of Buddhists in Tibet.“
