The shiitake mushroom, or just "shiitake"(椎茸) (Lentinus edodes or Lentinula edodes), is an edible mushroom. It is typically grown on a tree, such as shii, kunugi and oak.
The shiitake is also known as the Chinese black mushroom or black forest mushroom.[source?] It is also called "black mushroom".
There are two variant names. For high grades of shiitake there is dōnggū (冬茹: どんこ) ("winter mushroom"). Another is huāgū ("flower mushroom," (香信: こうしん) which has a flower-like cracking pattern on the mushroom's upper surface). Both are produced at colder temperatures.[source?] There are many cultivated varieties, which grow-up in a temperature at 7C - 26C. Most cultivars like cooler temperatures.
