Temperature is one of the important factors for the growth and development of Tremella Fuciformis. Tremella mesotherm. Mycelium can grow in the range of 16 °C ー30 °C, 20 °C ー28 °C can grow normally, 23ー25 °C is the best, and the mycelium is relatively weak under 20 °C or above 28 °C. The differentiation temperature of fruiting body is between 16 °C and 28 °C, the growth is too slow below 16 °C, and the differentiation is not easy above 28 °C. The ideal temperature should be between 22 °C and 25 °C.
