Establish your own working master culture with our premium King Oyster Agar Plate grown on Malt Extract Agar (MEA). King Oyster (Pleurotus eryngii) is produced from carefully selected commercial fruiting genetics chosen for vigorous mycelial growth, excellent fruiting performance, high biological efficiency, and reliable consistency. This fully colonized Petri dish provides a clean starting point for expanding onto agar, preparing liquid cultures, inoculating grain spawn, or maintaining long-term culture storage.
Every agar plate is prepared under strict sterile laboratory conditions and inspected before shipment to ensure a healthy, actively growing colony. King Oyster is prized for its thick, meaty stems, excellent shelf life, rich umami flavor, and exceptional culinary versatility, making it one of the world's most popular gourmet mushrooms. Agar plates are ideal for experienced cultivators, researchers, educational laboratories, and commercial mushroom growers seeking to preserve and propagate stable genetics without relying on spores.
