Hypsizygus marmoreus is a synonym of Hypsizigus tessellatus. Cultivation of Buna-shimeji was first patented by Takara Shuzo Co.,Ltd. in 1972 as hon-shimeji and the production started in 1973 in Japan. Now, several breeds are widely cultivated and sold fresh in markets.
Bunapi-shimeji (ja:ブナピー), known in English as the White Beech or White Clamshell Mushroom
Bunapi was selected from UV-irradiated buna-shimeji ('hokuto #8' x 'hokuto #12') and the breed was registered as 'hokuto shiro #1' by Hokuto Corporation.
Shimeji should always be cooked: it is not a good mushroom to serve raw due to a somewhat bitter taste, but the bitterness disappears completely upon cooking. The cooked mushroom has a pleasant, firm, slightly crunchy texture and a slightly nutty flavor. Cooking also makes this mushroom easier to digest. In stir-fried foods, as well as with wild game or seafood it is a good mushroom. Also it can be used in soups, stews and in sauces. When cooked alone, Shimeji mushrooms can be sautéed as a whole, including the stem or stalk (only the very end cut off), using a higher temperature or they can be slow roasted on a low temperature with a small amount of butter or cooking oil. Shimeji is used in soups, nabe and takikomi gohan.
Shimeji can also be anime or manga characters that roam around the screen. They're given this name because they multiply, just like the mushroom. They can also interact with windows. They are available on Windows, Mac OS, and GNU/Linux-based operating systems.
