We report the artificial cultivation of W0003, which is an edible fungus easy to cultivate because of rapid growth. The W0003 mushrooms has been grown on sterile sawdust with good yields in small and large scale experiments. The temperature at 15℃ appeared to be optimal for the fruiting, whereas the mycelium grew well up to 30℃. The pH range of 7 to 10 was the most favorable for the growth of the mycelium. Total yield obtained was 48.1% on the moistened media on the beech wood sawdusts supplemented with wheat bran.
