Blewit (Clitocybe nuda) is an eye-catching mushroom that produces smooth, medium-to-large lilac caps. When cooked, they have a meaty texture that is quite satisfying. Their delicious flavor is mild but distinct, often described as mushroomy and woody with a hint of pepper.

Blewit mushroom yields can be somewhat unpredictable, and they can pose some minor challenges with identification. Therefore, they are not ideal for first-time cultivators or those unfamiliar with how to properly identify different mushroom species. However, they can be quite rewarding to more experienced growers.

Recommended use:

  • Blewit sawdust spawn is only recommended for outdoor beds and top-fruiting containers.
  • Blewit sawdust spawn must combined with a substrate (like woody debris) in order to fruit.
  • Please note: Blewit mushrooms do not grow on logs.

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!

Cultivation

Inoculation

Depending on your conditions, blewit mycelium may be ready to fruit in 6-12 months. The ideal temperature range for this stage is between 40-70 degrees, and blewits need dips into below-freezing temperatures to cue mushroom formation. Often, this naturally happens in the fall after a full season of growing.

Similar to almond agaricus, blewits like a complex material to grow on. Consider making a blend of semi-composted manure, spent mushroom blocks, leaf litter, sawdust, kitchen scraps, grass clippings, cereal straws, and agricultural byproducts like bean hulls, corn stalks, etc. Use materials that are abundant and accessible in your area and avoid anything that’s potentially been sprayed by chemicals.

Recommended substrates: Partially composted yard waste such as hardwood leaves, grass clippings, twigs and tree bark. Composted mixtures of manure and straw or agricultural byproducts.

Storing

If you don’t plan to use your blewit mushroom sawdust spawn right away, store in the refrigerator. Use within 6 months of receipt.

Cooking

Once cultivated, the blewit mushroom has a full flavor that is evoked with thorough cooking. We recommend you use its sweet mild flavor as a compliment to autumn soups. Blewit mushrooms work best when sautéing and simmering, and are delicious in stews, omelets or fried in butter.

CAUTION: Be careful to properly identify these mushrooms when harvesting and before consuming. There are some poisonous purple mushrooms that can grow in similar habitats. Spore prints can be very helpful in distinguishing them from Cortinarius species of concern.

Ingredients

All our spawn is made using organic cultures from our own culture bank. Our sawdust spawn is handmade from a blend of locally sourced, all-natural, organic, and non-GMO woods and supplements from farms and forests in New England and North America.

Cautions & considerations

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.

Sawdust Spawn Frequently Asked Questions

Sawdust spawn is sterilized sawdust colonized with mushroom mycelium. It’s used to inoculate a growing substrate such as logs, wood chips, or outdoor garden beds to start mushroom growth.

It serves as the "seed" for your mushroom crop — transferring live, growing mycelium into your chosen growing medium.

Sawdust spawn is best for outdoor projects like logs, stumps, or garden beds and is slower to contaminate.
Grain spawn is ideal for indoor grows or bulk substrate inoculation because it colonizes faster but is more contamination-sensitive.

Sawdust spawn is mixed or packed into a substrate (like logs or wood chips) to inoculate it. Common methods include:

  • Drilling and filling holes in logs
  • Layering in outdoor wood chip or straw beds
  • Mixing with sterilized sawdust or wood pellets for bag cultivation

Most sawdust spawn performs best on hardwoods like oak, maple, or beech. Some species (like Wine Cap or certain Oysters) can tolerate small amounts of softwood in the mix.
