This study aims to reduce the production cost of mushrooms and therefore boost the income of mushroom producers. The addition of a 10% concentration of herb medicine refuse was adequate for promoting mycelium growth in Flammulina velutipes. A moisture content of 60% in the culture medium was adequate for promoting hyphal growth. The optimum temperature and humidity were 16℃ and 70%-85%, respectively. The average yield of Flammulina velutipes fruting body per 1,100 ml bottle was 275-282 g, which is similar to that of the control. The outbreak of diseases such as mildew and bacterial blotch in mushroom was never observed in the bottle treated with herb medicine refuse. Fewer deformed and second-class quality mushrooms were observed than in the control group. Deviation reduced, and mushroom growth was observed to be significantly uniform. The winter mushroom had a white fruiting body with a hemispherical shape. The diameter of the mushroom cap was 9.2-9.3 mm, stipe length was 12.7-12.8 cm, and thickness was 3.3-3.4 mm; these were almost the same as those in the control group. The partial hardness of winter mushrooms in both the experimental and the control groups showed that the stipe (54.6-57.3 g/cm2) is a little harder than the mushroom cap (46.8-47.6 g/cm2). The calories and nutrients per 100 g of mushrooms in the control and samples were similar to each other.
