Black Pearl Oyster Mushroom, Black Oysters, Black Kings, Shimofuri Hiratake
A kind of UFO in mushroom cultivation, this variety appeared a few years ago in Japan and quickly gained popularity in North America. Resulting from a cross between a European variety and a Japanese variety, Black Pearl offers an excellent compromise between eryngiis and oyster mushrooms.
They have a wider stem than oyster mushrooms, but less dense than eryngiis. Their rounded caps resemble eryngiis, with a color ranging from light brown to dark striped brown depending on maturity and growing conditions. They grow in clusters and are easier to cultivate than eryngiis.
Variety belonging to the pleurotus ostreatus family, Black Pearl offers a delicious flavor, close to that of oyster mushrooms with a more pronounced umami note. They are also very productive.
❄️ Storage: 1 month in the refrigerator.

I personally prefer them to grey oyster mushrooms.
