Pholiota nameko, commonly known as Nameko, is a small, amber-brown mushroom with a slightly gelatinous coating that is used as an ingredient in miso soup and nabemono. In some countries this mushroom is available in kit form and can be grown at home. It is one of Japan's most popular cultivated mushrooms, tasting slightly nutty and is often used in stir-fries.
In China the mushroom is known as huázĭ mó (Chinese: 滑子蘑).
In Russia, it is also consumed widely, and is known as (often sold as) "o-pyo-nok" (опёнок) or plural "o-pya-ta" (опята).
In America, the mushroom is sometimes called a "butterscotch mushroom".
Individual "shelves" range from 2-10 inches across. These shelves are made up of many tiny tubular filaments (hyphae). The mushroom grows in large brackets - some have been found that weigh over 100 pounds (45 kg). It is most commonly found on wounds of trees, mostly oak, though it is also frequently found on eucalyptus, yew, sweet chestnut, and willow, as well as conifers in some species. Laetiporus species produce brown rot in the host on which they grow.
