Lychee mushrooms, a rare specialty from the Guangdong region of China, are currently only naturally grown due to their scarce quantity and high demand. These mushrooms grow in damp termite nests on lychee trees and require specific weather conditions to develop. They are known for their sweet aroma and melt-in-your-mouth texture, and can be fully absorbed by the body, making them highly beneficial. The growth cycle of these mushrooms is approximately 20 days, and they sell for a high price of 1,400 CNY/kg due to their rarity and the destruction of termite nests, which can prevent their regeneration.
