Blue Oyster mushrooms, botanically classified as Pleurotus ostreatus var. columbinus, are a type of shelf fungus belonging to the Pleurotaceae family. Experts believe over two hundred different subspecies of oyster mushrooms exist, and the flat-capped fungi are considered one of the most cultivated mushrooms in the world. Blue Oyster mushrooms are primarily found in the northern hemisphere, growing in large, overlapping clusters on logs, stumps, and decaying trees.

The mushrooms have an aggressive nature, are fast-growing, and distinct from other oyster mushrooms as they are able to withstand colder cultivation temperatures. Commercially, Blue Oyster mushrooms are favored by mushroom growers for their unusual coloring, easy-to-grow nature, and fast colonization. The subspecies is also frequently sold through online retailers for home cultivation for novice growers.

Blue Oyster mushrooms have a mild, savory flavor well suited for cooked preparations, including braising, sautéing, roasting, frying, grilling, and sir-frying.

The mushrooms can be consumed raw, but the flavor may contain a slightly more metallic taste. Blue Oyster mushrooms are most commonly combined with other mushrooms and sauteed to create an earthy and textural side dish, or they are tossed into soups to contribute umami flavors into the broth. The mushrooms are also roasted and stirred into pasta, cooked into omelets, breaded and fried, prepared as a vegetarian substitute for seafood, used as a topping over pizza, grilled and layered onto burgers, or served as a simple side dish. In addition to fresh preparations,

Blue Oyster mushrooms can also be dried for extended use and do not have to be rehydrated before using. Blue Oyster mushrooms pair well with herbs such as parsley, thyme, and sage, potatoes, aromatics including garlic, green onion, shallots, ginger, and lemongrass, leeks, asparagus, bok choy, bell pepper, miso, heavy cream, fish, and meats such a beef, poultry, and turkey.

The mushrooms will keep up to three days when stored loosely in a brown paper bag in the refrigerator. It is advisable to keep the mushrooms in larger clumps for better storage to keep them from drying out. Once cooked, Blue Oyster mushrooms will keep for 2 to 3 days in the refrigerator, or they can be frozen for up to three months. Blue Oyster mushrooms can also be dried and kept in a sealed container away from direct sunlight for extended use.

For the most part happy with my orders

Last order I got was frozen when it was delivered. I know that's not your guys' fault. Lesson learned, refrain from ordering spores in the winter. Only one out of three syringes took, the blue oyster. Portobello and shiitakes have yet to show any signs of growth after almost a month. But like I said that's kind of out your guys control. Other than that I have been very satisfied with the spores I have gotten from you guys.

Thanks for the review! Sorry to hear about the freezing and lack of growth. Please keep in touch and i'll make sure you are taken care of!

Gorgeous Flushes

I put this straight to an all in one bag, and it grew out fully ready to fruit within two weeks! After putting into fruiting, i got not just one, not even two, but three MASSIVE flushes of gorgeous mushrooms 😎
