As one of the most widely cultivated mushrooms in the world, the Oyster Mushroom, Pleurotus, has been in commercial cultivation since the time of World War I. The White Oyster Mushroom, Pleurotus ostreatus was first cultivated in this manner.

Oyster Mushrooms come in many varieties, with over 200 species of them being edible. These mushrooms are indigenous to Britain, Ireland, most of Europe and Asia. Records indicate that the Oyster Mushroom was first identified in 1775 by a Dutch naturalist.

Oyster Mushrooms got their name from their distinctive shape, which many people believe look like an oyster. Some even claim they have a similar flavor and texture.
