   Hymenogastrales, Grifola frondosa
- in mid-temperature (optimum temperature 22-28 C, maximum 32 C) : oak-mushrooms
The pileus of the oak-mushroom is 4-10 centimeters in diameter, brown, round-shaped and the edges roll up inward at the early stage of growth, however, it flattens as it gets bigger. The oak-mushroom, as well known as the pine-mushroom is an Asian delicacy , not only in China.

The oak-mushroom grows naturally on dead, wide-leaf trees such as chestnut trees, while also being cultivated artificially. The flesh of the oak-mushroom is very firm and white, and the unique fragrance becomes stronger when dried. The gills are thin and white. The stem looks white but it's actually a tough brown fiber. The oak-mushroom is the representative edible mushroom of both Japan and Korea.
