Brown-black mushrooms are accidentally discovered in flat-grown mushrooms of civil air defense. Pleurotus sapidus Schulz, the Pleurotus sapidus Schulz cultivated in our country, was found in the summer of 1981. It was found that in the summer of 1981, a cluster of plants that grew very dark and dark was not only black-brown, but also the folds of the bacteria turned from white to beige. Short or sterile handle, spores printed lilac. Obtained by tissue separation bevel pure strains, and then the mutant strains of mushrooms bottle test. Medium recipe: 78% cotton seed, 20% bran, 1% gypsum powder, 0.5% urea, 0.5% magnesium sulfate. Feed water ratio of l: 1.6. After 30
