Red reishi (Ganoderma lucidum) is an edible medicinal mushroom known as “Ling Zhi” in China and “Reishi" or "Manetake” in Japan. It produces beautiful, reddish-brown, shelf-like fruiting bodies that are highly prized for their wellness properties. When fresh, the flat cap is soft and cork-like. Because it releases spores via pores, it lacks gills on its underside. And, depending on the age of the mushroom, the pores may appear brown, cream, or white.

Because red reishi can be difficult to cultivate, it is recommended for advanced and enthusiast growers. However, it can be extremely rewarding for those who have had some success growing other mushrooms.

Recommended use:

  • Red reishi sawdust spawn is only recommended for use in log projects.
  • One bag of sawdust spawn will reliably inoculate 20 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!

Tools you'll need

To grow on logs using sawdust spawn, you will need a Log Inoculation Tool, Log Sealing Wax, and Wax Daubers. 

For larger log projects you may also want to purchase an Angle Grinder Adapter and specialized 12mm drill bit.

Inoculation

This species of reishi mushroom grows well on oak, maple, and other hardwoods. Reishi works best when fully colonized logs are buried underground. Reishi likes any of the three log methods and colonizes in 12-24 months. It prefers oak logs and fruits in the summer. After a 1-year colonization period above ground, Reishi logs may be buried under 2 inches of topsoil to mimic its natural method of production. Mushrooms will fruit from the logs and emerge from the soil.

Storing

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

Cooking

Reishi is tough, woody, and bitter. For this reason, we don’t recommend it for culinary use. However, it can be dried and made into teas or powders. It can also be extracted to make tinctures.

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.
