Black Morel Mushroom

Scientific Name: Morchella importuna

Black Morel is a prized gourmet mushroom known for its conical honeycomb-like cap and intensely earthy, nutty flavor. Highly sought after by chefs and foragers alike, it has a chewy, meaty texture that pairs beautifully with cream, butter, or wine reductions. Nutritionally rich, it offers a good source of iron, vitamin D, and antioxidants. Although morels grow prolifically in the wild, indoor cultivation is extremely complex due to their mycorrhizal tendencies and need for seasonal cues. Commercial outdoor cultivation has shown promise using sclerotia-based techniques in temperate zones.

Substrate: Outdoor soil beds enriched with hardwood chips, ash, and limestone; sometimes grown on grain to form sclerotia before soil inoculation

Colonization Temp: 55–65°F

Fruiting Temp: 40–60°F (after cold shock)

Fruiting Humidity: 70–85%

Light: Full or dappled daylight outdoors

FAE: Natural outdoor airflow

Notes: Requires overwintering or a cold-induced fruiting trigger; best suited for outdoor spring or fall fruiting beds.

Cultivation Difficulty: Pro

About Our Grain Spawn: Built on the same Unicorn 4T-INJ bag platform as our sterilized grain, this spawn is inoculated to order with low-passage, agar-verified culture for clean, vigorous growth. Because it’s freshly inoculated, the bag will arrive partially colonized—or colonization may become visible within a few days, depending on species and shipping conditions. Hydration and gas exchange are tuned for fast, even colonization.

How are grains pepared?

While other methods may work, we prioritize quality and consistency. We utilize a thorough clean, soak, heat, and strain method that fully prepares the grain before sterilization. This additional effort results in a more consistent, high-quality grain that optimizes mycelium colonization and ensures stronger, healthier growth.

What type of mushroom bag do you use?

We only use the industry standard Unicorn Bags. 3 pound bags use 4T-INJ Bags and the 5 pound bags use a 3T. Both Include a 0.2-micron filter patch for controlled airflow and a secure injection port, facilitating easy inoculation with liquid cultures or spore syringes.

Are spawn bags delivered fully colonized?

Colonization rates upon receipt will vary based on variety, transit time and temperature. Grains are Inoculated to order, so in most cases you will see visible mycelial growth upon receipt, but it's possible this will not occur until a couple days after. This depends on species and temperatures the grain spawn is exposed to during transit.

How should grain spawn be stored during colonization?

Keep in a cool, dark place during and after colonization. Once the bag reaches ~25% colonization, perform a gentle break and shake to redistribute mycelium and speed completion. Avoid opening until fully colonized and ready to expand into your substrate.
