Oyster mushrooms have a slightly chewy texture and are soft with a bittersweet aroma reminiscent of anise. When cooked, they have a mild and nutty, seafood-like flavor.
Pleurotus ostreatus, the pearl oyster mushroom or tree oyster mushroom, is a common edible mushroom. It was first cultivated in Germany as a subsistence measure during World War I and is now grown commercially around the world for food. It is related to the similarly cultivated king oyster mushroom.
