Description: King Oyster is large, heavy, fleshy, and unlike any other cultivated Oyster mushroom. Although quality varies, the dense bright-white stalks and creamy concave tan caps are usually thick and solid. This mushroom grows in clusters which join at the base and not in overlapping caps like other Oyster mushrooms. It is sweet and meaty and often grows on the decaying roots of plants in the carrot family. It can also be cultivated on chopped straw. As with all Oyster mushrooms, King Oysters need plenty of fresh air to develop normally. High carbon dioxide levels from mushroom metabolism will accumulate in sealed growing environments and can reduce cap size and elongate stems severely. Fruiting in open humidity chambers with frequent fresh air exchange will produce best possible yields.
