Oyster mushroom
Austern-Seitling · (Pleurotus ostreatus)
Oyster mushroom family (Pleurotaceae)
Description
The oyster mushroom (Pleurotus ostreatus) is an edible culinary and medicinal fungus with shell- or oyster-shaped caps in grey to brown shades and a lateral or off-centre stem. It grows in clusters on hardwood, especially beech, and is cultivated commercially worldwide on straw, sawdust and even spent coffee grounds. The mushroom is high in protein and contains beta-glucans as well as the natural statin lovastatin, making it valued both in the kitchen and in nutrition and health research. Its mild, slightly anise-like flavour and firm texture make it one of the most widely cultivated edible mushrooms in the world.
