Prolonged drought and heatwaves in southern China have led to a significant decrease in the matsutake mushroom harvest, resulting in a surge in prices. The harvest in some production areas in Yunnan, a major producer of matsutake, has fallen by up to 90%. The scarcity is linked to climate change, with China experiencing its worst heatwave in 60 years. Prices were expected to decline but have remained high due to the severe reduction in production.
