And then we have dried Nameko Mushrooms (Pholiota nameko - aka Butterscotch mushroom). In Chinese, 滑子蘑 (huá zi mó).
These are a very popular cultivated mushroom in Japan. They are small (the cap is about the size of my thumbnail), have a gelatinous coating and are mainly used as an ingredient in miso soup. They are also sometimes stir fried.
In China, they are less well known but are also occasionally used in soups, hot pots and stir fries. Overcooking tends to make them more gelatinous to the point where many people begin to find them unpleasant.
