Chestnut (Pholiota adiposa) is a popular cultivated mushroom in Japan. It produces velvety, small-to-medium, delightfully speckled caps resembling the color of their namesake nut. When cooked, they have a woodsy aroma, a meaty heaviness, and a rich, nutty, mildly-sweet flavor.

Chestnut mushrooms aren't too difficult to cultivate, but can pose some minor challenges with identification. They are not ideal for first time cultivators or those unfamiliar with how to properly identify different mushrooms species. However, this species can be quite rewarding to grow and can be produced commercially.


Chestnut mushroom sawdust spawn can be used for log projects and/or outdoor beds and containers.

To grow on logs, you need an Inoculation Tool. For larger projects you may want to purchase an Angle Grinder Adapter and specialized 12mm drill bit.

Sawdust spawn is ideal for larger mushroom log projects (10 or more logs) or for use by those wanting to inoculate logs every year.


If you don’t plan to use your chestnut mushroom sawdust spawn right away, store in the refrigerator. Use within 6 months of receipt.


LOGS: Chestnuts work well with the Stump and Log methods in maple and oak logs. After a 1-year colonization period above ground, Chestnut logs may be buried under 2 inches of top soil. Mushrooms fruit from logs and will emerge from the soil.

Once cultivated, the Chestnut mushroom has a full flavor that is evoked with thorough cooking. We recommend you use its rich, nutty flavor as a compliment to autumn soups. Chestnut mushrooms work best when sautéing and simmering, and are delicious in a variety of soups, stews, and casseroles.

CAUTION: Be careful to properly identify these mushrooms when harvesting and before consuming. Chestnuts have poisonous lookalikes, so make sure you are familiar with the deadly Galerina autumnalis.

All things Mushroom (substrate, grow kits, spawn, etc.) are shipped separately from seeds. The flat shipping rate per order for Mushroom goods is $10.00.
