The invention relates to the technical field of edible mushrooms. A method for cultivating mushrooms of tremella aurantialba is suitable for the cultivation of the tremella aurantialba, the growth speed of mycelia is high, the mycelia is pure white and dense, the growth vigor is strong, the fruiting bodies are compact, the biological traits are good and the yield difference reaches an extremely significant level; and a suitable substrate formula for tremella aurantialba cultivation is obtained, so that the yield of the tremella aurantialba is improved, the purpose of tremella aurantialba efficient cultivation is realized. According to the method for cultivating the mushrooms of the tremella aurantialba, the lighting, the temperature, the humidity and the ventilating of a mushroom fruitingperiod are set, and the lighting, the temperature, the humidity and the ventilating in the mushroom fruiting period directly affect the yield and the quality of the fruiting bodies of the tremella aurantialba, so that the growth status of the fruiting bodies can be ensured, and the phenomenon of a large number of rotten mushrooms and misshapen mushrooms is prevented; and the tremella aurantialba has geotropism, so that layered putting including an upper layer, a middle layer and a lower layer is adopted when mushroom bags are put, mushroom openings face downwards or face the side face, a largeamount of moisture can be prevented from accumulating, the generation of the misshapen mushrooms is reduced, and thus the qualification rate of the tremella aurantialba is improved.
