Black Pearl King Oyster Mushroom Liquid Culture

Live, lab-tested Black Pearl Oyster liquid culture in a ready-to-inject 10ml syringe. A King Oyster hybrid with dark caps, thick stems, and the best traits of both parents.

Black Pearl is a cross between the common oyster and the King Oyster, and it inherits the useful half of each. From the King it takes a thick, dense, fully edible stem and a firm meaty bite. From the common oyster it takes speed, forgiveness, and heavy clustered flushes.

The caps come in a deep charcoal to near-black that stays dark through cooking, which makes it as striking on the plate as it is in the fruiting chamber. The flavor is more pronounced than a Blue Oyster — savory, slightly earthy, with real umami depth when seared.

If you have grown oysters successfully and want to step toward King Oyster without its fussiness, this is the bridge. It rewards good fresh air exchange with thicker stems and better-formed caps, but it will not punish you the way a true King will.
