Almond agaricus (Agaricus subrufescens) has a sweet earthy fragrance and is easier to grow than its mushroom cousins (button, cremini, and portobello.) In fact, it thrives on compost! Almond agaricus is fast substrate colonizer and has a sweet, fragrant almond scent.

If grown in well-cared-for beds in warmer temperatures, it's a reliable producer. Similar to button mushrooms, Almond agaricus grows in compost, but does not require pasteurization. It's an ideal mushroom for those who have some experience gardening with other mushroom species, like wine cap or oysters.

Recommended use:

  • Almond agaricus sawdust spawn is only recommended for use in outdoor beds.
  • Almond agaricus sawdust spawn must combined with a substrate (like compost) in order to fruit.
  • Please note: Almond agaricus does 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

Take note that Almond Agaricus mycelium will die under 35 degrees F. You should only plant when the average temperatures are consistently above 50 degrees F.

Almond Agaricus beds are made by sprinkling spawn and top coating with 3-4 inches of composted substrate. You may choose to inoculate areas underneath garden plants to make use of this shade loving crop. Almond Agaricus loves warmth (remember to never put the spawn in the fridge!)

Beds do particularly well in greenhouses or high tunnels, which will also help extend the season of your Almond Agaricus crop. It is unlikely that your Almond Agaricus crop will overwinter unless it is in a greenhouse, but if it is well-mulched in the fall you may see growth the following season. It is more likely to see second year growth in warmer climates.

Beds should ideally be made from fully finished compost and be at least 3-4 inches deep. One bag of spawn should be enough for a 4 ft by 4 ft area. When the bed begins to show mycelial growth (you can gently brush some compost aside and should see white strands of mycelium running through your compost bed) you should case it with lime treated peat moss or straw. Water the casing and keep an eye out for mushroom pins.

Storing

Do not refrigerate almond agaricus sawdust spawn.

Store at room temperature, away from direct sunlight. Use almond agaricus sawdust spawn within 6 months of receipt.

Cooking

Almond Agaricus is in the same family as cremini, button mushrooms, and portobello mushrooms and can easily replace all of those varieties in most recipes and pair well with many cuisines and flavors. They retain water and may develop a viscous texture when undercooked. If you prefer a firm or dryer texture, continue to cook Almond Agaricus until their liquid has reduced and cooked off and they begin to brown.

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.
