Our USDA-certified organic beech (Hypsizygus tessellatus) grain spawn features a strain with a lightly sweet, savory and nutty flavor, and subtly crunchy texture. Beech is a slow-growing mushroom that is found on beech trees in the wild, hence the name. Native to East Asia, they are perfect in soups, stews, stir-fries, or sauces, and maintain their crisp texture if added as the final ingredient. Beech can be a bit finicky, but generally grows well indoors. They require high CO2 levels to achieve delicate, long stems, but can also be fruited like oysters. They prefer cooler temperatures, and when they grow successfully, you can expect significant and commercially-viable harvests.
Recommended use:
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!

Beech mushrooms have a crunchy texture that offers a delicately mild flavor that is both satisfyingly sweet and nutty. They may be eaten in clusters or individually separated. To separate, trim off the base of the cluster and they are clean and ready-to-cook. To sauté, melt butter in a small sauce pan over medium-low heat. Add the mushrooms and cook them gently, stirring frequently, until they are tender.
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.
