King Oyster/Trumpet Information

King Oysters are an extremely dense and meaty mushroom in the Oyster family. It’s also the largest of the Oyster mushrooms. King Oysters go by the name “Trumpets” or “King Trumpets” as well due to their trumpet-like appearance. This species is native to the Mediterranean regions of Europe, North Africa, and the Middle East. Luckily, when cultivated indoors, it can be grown almost anywhere! 

King Oysters are gourmet mushrooms that are held in high regard. They’re prized for both their flavor and texture. In Asia, King Oysters are a commercially cultivated species of mushroom as they are used commonly in Asian cuisines. 

Something interesting about King Oysters is that like others in the Pleurotus genus, it does colonize decaying wood, but it is also known to grow via parasitic relationships with the root systems of herbaceous plants. They can also be found growing from the roots of hardwood trees in a more symbiotic relationship rather than parasitic.
