Oyster mushroom
The Oyster mushroom, or Pleurotus ostreatus, is a common mushroom prized for its edibility. Long cultivated in Asia, it is now cultivated around the world for food. It is related to the similarly cultivated "king oyster mushroom". Oyster mushrooms can also be used industrially for mycoremediation purposes. Additional recommended knowledge
NameBoth the Latin and common name refer to the shape of the fruiting body. The latin pleurotus (sideways) refers to the sideways-growth of the stem with respect to the cap while the latin ostreatus (and the English common name, oyster) refers to the shape of the cap which resembles the bi-valve of the same name. Many also believe that the name is fitting due to the flavor resemblance to oysters. In Chinese, they are called píng gū (平菇; literally "flat mushroom"). The oyster is one of the more commonly sought wild mushrooms, though it can also be cultivated on straw and other media. It often has the scent of anise due to the presence of benzaldehyde.

Edible usesThe oyster mushroom is frequently used in Japanese and Chinese cookery as a delicacy: it is frequently served either on its own, although sometimes stuffed: and in stir-fry recipes too with soy sauce. Additional InformationOyster mushrooms are a natural source of statin drugs. Studies have shown that they typically contain 0.4% to 2.7% statins on a dry weight basis. Z. Naturforsch Study. A number of studies on lab animals have shown that adding Pleurotus to the diet can reduce cholesterol under some conditions. The oyster mushroom is also one of the few known carnivorous mushrooms. Its mycelia can kill and digest nematodes. This is believed to be a way to obtain nitrogen. Oyster mushrooms contain a small amount of arabitol which can cause gastrointestinal distress in some people.
