Nameko
Pholiota microspora
A small Japanese mushroom with an amber, gelatinous cap, the star of miso soup. It likes the cold and is grown on hardwood logs laid down in humid shade.
Partial shade
Role in permaculture
A decomposer of thinning or pruning logs in a cool, humid climate, on a log station in the shade, close to the shiitake's role.
Growing this mushroom
- Method
- Hardwood logs laid down or half-buried, in a cool climate
- Substrate
- Fresh hardwood logs (beech, oak, alder, poplar), often laid on the ground or partly buried and covered with leaves to keep the humidity.
- Where to place it
- Logs in cool, humid shade: north of a building, under the cover of a hedge or trees. Poorly suited to wood-chip paths in full sun, which offer it neither the shade nor the log humidity it needs.
- Period
- Inoculation in late winter or spring; fruiting in autumn, the species liking cool temperatures.
- Level
- Intermediate
Steps
- On fresh hardwood logs, drill and inoculate with dowels (plugs) or seeded sawdust, then seal with wax.
- Place the logs in cool shade, on the ground or slightly buried, covered with leaves, and keep humid.
- Let it colonise about a year.
- Harvest in autumn, when the cold triggers fruiting, in clusters with the characteristic viscous cap.
Precautions
Important identification vigilance: several brown mushrooms growing in tufts on dead wood can be confused, including the funeral bell (Galerina marginata), DEADLY. Only harvest and eat specimens from your own controlled inoculation, or have any foraging validated by a mycologist. At the slightest doubt, abstain.

Nutritional & medicinal properties
For educational purposes. Not a substitute for medical advice. Effects depend on the form, the dose and personal context.
Precautions & contraindications
To be eaten cooked (ANSES: never eat a mushroom raw). The wild form, brown and growing in clusters on wood, exposes one to a DEADLY confusion with the funeral bell (Galerina marginata): only eat specimens from a controlled inoculation or validated by a mycologist (see the cultivation section).
Key takeaways
