Flammulina velutipes is a highly regarded mushroom especially in Japan where is called Enokitake (one English pronunciation /ɪˌnkiˈtɑːk/)(榎茸, エノキタケ, Japanese pronunciation: [enokitake], also enokidake (榎茸, エノキダケ, Japanese pronunciation: [enokidake], futu (in India) or enoki (榎, エノキ, Japanese pronunciation: [enoki],[1] is a long, thin white mushroom used in East Asian cuisine (such as that of China, Japan, Vietnam and Korea). These mushrooms are cultivars of Flammulina velutipes (Grnus Flammulina), also known by the name golden needle mushroom, futu mushroom or lily mushroom. Wild forms differing in color, texture, and sliminess are called names including futu, seafood mushrooms, winter mushrooms or winter fungus, velvet foot, velvet stem or velvet shank.[2]

This mushroom is available fresh or canned. Should be paid attention, while picking it from the wild, to not confuse it with the Galerina specimens[3], Flammulina velutipes can be recognised from Galerina by the firm, white, shiny caps, rather than those from Galerina with slimy or brownish stalks that should be avoided.[4] It is traditionally used for soups but can be used for salads and other dishes. The mushroom has a crisp texture and can be refrigerated for approximately one week.[5]

Features[edit]

The mushroom naturally grows on the stumps of the Chinese hackberry tree (Celtis sinensis, "enoki" in Japanese) and on other trees, such as ash,[which?] mulberry and persimmon trees.

There is a significant difference in appearance between the wild and cultivated types of the mushroom. Cultivated mushrooms have not been exposed to light, resulting in a white color, whereas wild mushrooms usually display a dark brown color. Cultivated mushrooms are grown in a carbon dioxide (CO2)-rich environment to nurture the development of long thin stems, whereas wild mushrooms produce a much shorter and thicker stem.

The wild variety of the mushroom may be found from September through to March, hence the name winter fungus.

The names enokitake (榎茸エノキタケ), enokidake (榎茸エノキダケ) and enoki (エノキ) are derived from the Japanese language. In Mandarin Chinese, the mushroom is called 金針菇 (jīnzhēngū, "gold needle mushroom") or (jīngū, "gold mushroom"). In India it is called futu, in Korean, it is called paengi beoseot (팽이버섯) which means "spinning top mushroom", and nấm kim châm in Vietnamese.

Health properties[edit]

Enokitake mushrooms contain antioxidants,[6][7] like ergothioneine.[7] Animal testing has indicated possible applications in the development of vaccines and cancer immunotherapy.[8]

Research at the National University of Singapore, first published in 2005, stated that the stalk of the golden needle mushroom contains a large quantity of a protein, named "Five"/"FIP-fve" by the researchers, that helps in the regulation of the immune system. The mushroom also contains Flammutoxin, a cytolytic and cardiotoxic protein[9][10] that has proven to be non-toxic when absorbed/taken orally.[11]
