This morel strain (Morchella exuberans) is one of the most prized wild edibles. It produces large, pitted fruiting bodies with a unique texture and rich flavor. Unlike many cultivated mushrooms that have a robust meaty flavor, morels are best described as woody, nutty, and earthy.

Morels are a famously difficult mushroom species to cultivate but are great for experimenting with new methods. Given their difficulty, we do not currently recommend for commercial use. (Please let us know of your successes and failures when trying to cultivate this species!)

Recommended use:

  • Morel sawdust spawn is only recommended for use in outdoor beds or in forest floor inoculations.
  • Morel sawdust spawn must combined with a substrate (like compost mixed with wood ash) in order to fruit.
  • Please note: Morel 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!

Inoculation

We consider this an experimental spawn strain which will benefit from cultivation trials in burned substrate.

Our Morel culture was obtained from fruiting specimens in burnt pitch pine forest in New England. Known colloquially as ‘greenies’ in the western U.S., burn Morels are extremely rare in Northern New England. 

Storing

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

Cooking

Morels make a great accompaniment to meats, fish, and risottos. Larger morels may be stuffed and grilled, baked, or sautéed.

Always cook morel mushrooms thoroughly. Morels should not be eaten raw or consumed in large quantities because they contain a toxic substance which is only destroyed when cooked.

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.
