The Oyster Mushroom
Pleurotus ostreatus
The Oyster mushroom, or Pleurotus ostreatus, is an extremely common edible mushroom and is often grown in growing kits by enthusiasts. It has been cultivated in Asia for centuries and is still used today. Another common use of the oyster mushroom is for industrial mycoremediation.
Identification of the Oyster Mushroom
- Cap: 5-25 cm broad, fan or oyster-shaped; Natural specimens
range from white to gray or tan to dark-brown; margin inrolled when
young, smooth and often somewhat lobed or wavy. Flesh white, firm,
varies in thickness due to stipe arrangement.
- Gills: Gills are white to cream, descend stalk if present. If so, stipe off-center with lateral attachment to wood.
- Spores: The spores form a white to lilac-gray print on dark media.
- Stipe: Often absent. When present it is short and thick.
- Taste: Mild
- Odor: Often has a mild scent of anise.
Toxic Look-alikes
The only look-alike is Omphalotus nidiformis which grows in Australia and Japan.
