oyster cap

The oyster mushroom, scientifically known as Pleurotus ostreatus, is an edible fungus that typically grows on deciduous trees and deadwood. The king oyster mushroom (Pleurotus eryngii) is a widely cultivated variety known for its meaty texture and umami taste. These fungi are rich in protein and B vitamins, phosphorus, potassium, selenium, and copper.12

King oyster mushrooms are saprotrophic, meaning they feed on decaying organic matter, often growing from the roots of dead hardwood trees. They are also found in association with plants in the carrot family. Commercially, they are cultivated in controlled environments using substrates like hardwood sawdust. In cooking, they are versatile and can be roasted, stir-fried, grilled, or sautéed, often serving as a meat substitute.2
