Florida Oyster Mushroom Pleurotus ostreatus, the grey/Florida 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. The oyster mushroom is one of the more commonly sought wild mushrooms, though it can also be cultivated on straw and other media. It has the bittersweet aroma, which is also characteristic of bitter almonds. Both the Latin and common names 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 bivalve of the same name. Many also believe that the name is fitting due to a flavor resemblance to oysters. The name oyster mushroom is also applied to other Pleurotus species, so P. ostreatus is sometimes referred to as the tree oyster mushroom or the grey oyster mushroom to differentiate it from other species in the genus.
