The Black Pearl King Oyster mushroom is a relatively new hybrid from Japan that is a cross between a European strain and an Asian strain of Oyster mushroom. King oysters are the largest species in the oyster mushroom family.
Black Pearl King Oysters have a hearty texture and an earthy, umami flavor that's perfect for a main entree or side dish. You can use the entire mushroom – the cap and the stem – as this variety has a soft stem. This mushroom is packed with nutrients such as iron, zinc, calcium, folic acid, potassium, phosphorus and selenium, along with vitamins C, D, B1, B3, B5, & B12.

Mushrooms need to be able to "breathe" so that they stay fresh. All mushrooms should be stored in the paper bag or cardboard container you receive them in. If you need to separate into smaller amounts, use an open plastic container and put a double layer of paper towels on the top and bottom of the mushrooms.
They should be stored in the crisper drawer or as close to the bottom of your refrigerator as you can. They may freeze on the upper shelves.
Don't worry if they do freeze. Most mushrooms can be frozen and thaw out just fine. That is an option for longer term storage.
Mushrooms can also be dehydrated for long term storage.
