King Tuber Oyster Mushroom Grain Spawn

Grow the Giants with NuvoSpawn’s King Tuber Oyster Mushroom Spawn!

Step into the world of gourmet cultivation with King Tuber Oyster (Pleurotus tuber-regium): a truly special mushroom that produces not just delicious oyster mushrooms but also edible underground sclerotia, often called “tubers.” With NuvoSpawn, you get high-quality, vigorous grain spawn engineered for reliable growth and abundant harvests.

King Tuber Oyster (Pleurotus tuber-regium)

Not only does it produce thick, meaty oyster mushrooms, but it also forms underground sclerotia (tubers)—dense nutrient-rich structures long prized in African and Asian traditional medicine.

King Tuber is abundant in dietary fiber, protein, and antioxidants, along with polysaccharides studied for their immune-supporting, anti-inflammatory, and gut health–boosting properties. The tubers are especially valued for their ability to store for long periods, making them a reliable functional food source.

With its robust, earthy flavor and firm texture, King Tuber Oyster is both a culinary and medicinal mushroom. The fruiting bodies are delicious when stir-fried, grilled, or used in hearty soups, while the tubers are often dried, powdered, or incorporated into traditional dishes. Its versatility makes it a standout choice for growers who want more than just a mushroom harvest.

Temperature: For this variety, we recommend a range of 22°C–32°C for healthy growth, with warmer tropical/subtropical conditions being especially favorable for sclerotia formation. Slightly cooler environments encourage more consistent fruiting of the mushroom bodies.
