The King Oyster Mushroom (Pleurotus eryngii) stands as a towering figure in the mushroom world, boasting a substantial, meaty texture and a rich, umami flavor that has endeared it to chefs and food enthusiasts worldwide. This species' versatility in the kitchen is unmatched, serving as an excellent meat substitute in a variety of dishes. Its cultivation process is straightforward, making it a rewarding endeavor for growers at the intermediate-beginner level and beyond.

The King Oyster is particularly noted for their ability to fruit in cooler temperatures, requiring a brief “cold shock” to help induce the formation of mushroom pins. Following this phase, the temperature can be increased within their preferred fruiting range to encourage growth. The robust nature of this mushroom, coupled with its delicious flavor and texture, makes it an outstanding choice for both commercial cultivation and home growers seeking to explore the fascinating world of mushroom farming.

Grow on: Supplemented hardwood sawdust or Straw. King Oyster mushrooms show a distinct preference for oak and beech substrates. When supplemented, these materials set the gold standard for the cultivation of King Oyster mushrooms, promoting optimal growth and yield. This substrate choice yields a Biological Efficiency typically ranging from 65-80%, showcasing the mushroom's robust growth capability.

Fruiting conditions: King Oyster mushrooms require a slight drop in temperature to initiate pinning, thriving in environments ranging from 15-21°C. The mushrooms benefit from high relative humidity levels of 85-90% and demand consistent fresh air exchange to develop properly.

Preferred agar culture media: MYPA (Malt Yeast Peptone Agar), PDYA (Potato Dextrose Yeast Agar), Malt Extract Agar (MEA)

Also Known As: King Trumpet Mushroom, French Horn Mushroom, King Brown Mushroom, Boletus of the Steppes.

King Oysters excel in rapid colonization, making them an excellent choice for novice growers. However, they thrive under cooler conditions and necessitate temperature and humidity management to mitigate the risk of blotch, ensuring a successful cultivation.
