|Certifications||USDA certified organic|
|Bag weight||6 lbs|
Our USDA-certified organic nameko (Pholiota nameko) grain spawn features a popular strain that's widely cultivated in Japan. As these mushrooms grow, they are covered in a layer of natural gelatin which gives them a unique, almost shiny appearance. When cooked, nameko has an earthy flavor with subtle fruit-like hints, and an aroma reminiscent of cashews and butterscotch. Because they need cooler temperatures and constant humidity when fruiting, they require patience and precision. They are not ideal for beginners but can be quite rewarding for experienced growers.
- Nameko grain spawn can be used for indoor production using sawdust-based sterilized substrate.
- Do not use grain spawn for log inoculation.
- This is not a mushroom grow kit. Nameko grain spawn must be combined with a substrate in order to fruit.
Upon receiving your spawn:
Remove it from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive!

Nameko is a lesser known culinary mushroom in the Americas, but it is used widely in East Asia. It has a gelatinous cap that can thicken soups and sauces and has an aroma that walks the line of being both fruity and earthy. Nameko mushrooms go well with dark green vegetables, red meats, and shallots, and are used traditionally in Japanese miso soups.
Our grain spawn is USDA certified organic and made using organic cultures from our own culture bank. It contains a blend of locally sourced, organic, and non-GMO grains and supplements from farms in New England and North America.
If you’re going to consume home-grown mushrooms, make sure to cook your fresh mushrooms thoroughly with heat. If it is your first time eating this species, it is best to start with a small amount to check for allergies, even if cooked.
