North Spore Golden Enoki (Flammulina velutipes) grain spawn features a cultivated strain that produces elegant clusters of slender, golden-yellow mushrooms with long, threadlike stems and petite button-like caps. A staple in East Asian cuisine, Golden Enoki offers a crisp texture and mild, slightly fruity flavor that deepens when cooked—perfect for soups, stir-fries, and hot pots.


Golden Enoki is a rewarding indoor variety, particularly suited to cooler temperatures and high humidity. When grown under the right conditions, it can produce generous first and second flushes, making it a great option for small-scale commercial growers and serious home cultivators alike. Though more cold-tolerant than tropical oysters, Golden Enoki prefers stable environmental control for best results.


Golden Enoki grain spawn is ideal for indoor cultivation and should be kept out of direct sunlight and dry environments. It may fruit outdoors in spring or fall in cooler regions, but it is best known for its performance indoors under controlled conditions.

Recommended use:

  • Shiitake grain spawn can be used for indoor production using sawdust or straw.
  • Do not use grain spawn for log inoculation.
  • This is not a mushroom grow kit. Shiitake 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!
