Our USDA-certified organic lion's mane (Hericium erinaceus) grain spawn features a strain that produces plump, dense, shaggy mushroom clusters with a consistency and flavor similar to crab meat. This mushroom is highly versatile and can be enjoyed cooked, dried, extracted, or even steeped as a tea!
While slightly more difficult to get flushes than oysters, lion's mane is great for confident beginners and is a reliable indoor year-round producer. And, if kept in the right conditions, it will yield substantial first, second, and even third harvests (making them an ideal commercial variety!) Note that lion's mane can be prone to drying out if the ambient humidity is too low.

Recommended use:
- Lion's Mane grain spawn can be used for indoor production using sawdust-based sterile substrate.
- Do not use grain spawn for log inoculation.
- This is not a mushroom grow kit. Lion's mane 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!

Its unique flavor and consistency make it ideal as a seafood substitute in recipes. We like to slice it into rounds and pan-fry it in olive oil or butter. We also recommend ripping it up and making vegan or vegetarian crab cakes with it. You can find some amazing recipes online!

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 ingredients 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.

It was good! You got them to quickly. I expanded into more grain spawn as well as made some bags to fruit with. I’m still using the grain I expanded with. Thanks so much for keeping my farm in mushrooms!

Excellent product
Due to how busy my life had been for a few weeks, I had forgotten I had ordered this spawn bag and normally these things won't fruit if there is no substrate but somehow it was fruiting. I was shocked with the quality of it and am very pleased.

Thanks for sharing, Sophie! Our team is here if you need anything!
3 out of 4 ain't bad
Three of the 4 grain spawn were fully colonized. The shitake shown little colonization and has not made progress yet. This has not been the typical level of quality that I have come to expect from North Spore.
