✅ Edibility Note
CHOICE EDIBLE: One of the most popular cultivated mushrooms worldwide with excellent flavor and texture. Wild specimens are safe and delicious when properly identified. Cook thoroughly before eating as raw oyster mushrooms can cause digestive upset in some people. Avoid older specimens that may be tough or insect-infested. Widely cultivated commercially, making it familiar to most people.

Common Lookalikes
Always verify identification to avoid these similar species:
- Pleurotus pulmonarius (nearly identical, paler, summer fruiting)
- Angel wings (Pleurocybella porrigens) - toxic, smaller, pure white, on conifers
- Crepidotus species - brown spores, smaller, different texture
- Elm oyster (Hypsizygus ulmarius) - central stem, less pronounced oyster shape
