Pleurotus Eryngii

Common Names: King Oyster, King Trumpet, French Horn









Pleurotus eryngii, widely known as the King Oyster Mushroom, is a prized edible fungus that is celebrated for its remarkable size, texture, and flavor. Native to the Mediterranean regions of Europe, the Middle East, and North Africa, and also found in parts of Asia, this mushroom has gained popularity across the globe due to its culinary versatility and substantial nutritional profile. King Oyster Mushrooms are distinctive for their thick, meaty white stems and relatively small, tan caps, unlike other oyster mushrooms which typically feature larger caps and smaller stems. Their robust structure allows them to maintain texture and flavor when cooked, making them a favorite ingredient in a variety of dishes. They can be sautéed, grilled, roasted, or stir-fried, and are often used as a substitute for meat in vegetarian and vegan recipes because of their hearty consistency and umami flavor.

Differences: the Jack O'Lantern mushroom has a bright orange color, compared to the white to tan color of the King Oyster mushroom. Furthermore, the gills of the Jack O'Lantern mushroom are bioluminescent and can glow in the dark, a feature not present in the King Oyster mushroom. It's crucial to note that while the King Oyster mushroom is edible and highly prized, the Jack O'Lantern mushroom is poisonous and can cause severe gastrointestinal distress if consumed.

  • Chemical analysis, moisture-preserving, and antioxidant activities of polysaccharides from Pholiota nameko by fractional precipitation

  • This study explored Pholiota nameko (P. nameko) polysaccharide fractions, PNP-40, PNP-60, and PNP-80, purified by gradient concentrations of ethanol (40%, 60%, and 80% (v/v)). The physicochemical properties, functional group composition, moisture-preserving, and antioxidant ability were determined. The results indicate that the polysaccharide contents of PNP-40, PNP-60, and PNP-80 are 45.12%, 78.04%, and 72.22%, respectively, while the β-glucan, protein, and uronic acid contents are 20.20%, 12.20%, and 10.15%, respectively; 11.24%, 14.53%, and 26.94%; and 5.99%, 7.73%, and 3.78%. Furthermore, PNP-60 has better moisture absorption, while PNP-80 has better antioxidant ability and H2O2-injury resistance activity

  • In May 1950 my husband undertook a pilgrimage to remote Serignan to see the Fabre water-colors, and he picked out more than a dozen for our book. Two years later, finding himself again in Paris, he called once more on Professor Heim, who by now had become the Director of the Museum National, a worthy successor in that great post to the illustrious Buffon. Indeed, he sits at Buffon's very table, in Buffon's very room, where the elegant i8th century furnishings have remained unchanged, the walls adorned with the graceful i8th century oils of Jean-Jacques Bachelier, depicting the birds of the several continents.

Our public is certainly one of the smallest in the English-speaking world, but no matter. We invite all to share our joys, and if few respond, we are not less happy for being few to savor the secret.
