Discover the striking beauty and unique presence of the Organic Hemlock Reishi Mushroom Plug Spawn from North Spore. Known scientifically as Ganoderma tsugae and commonly as "hemlock varnish shelf," this distinctive mushroom enriches any outdoor growing space.

Our plug spawn offers a reliable method for cultivating this captivating species on logs and stumps.

As a USDA Organic certified product, it ensures you are introducing pure, high-quality mycelium into your forest or garden ecosystem.

The Hemlock Reishi produces elegant, shelf-like fruiting bodies. These are characterized by a beautiful, shiny brownish-orange varnish top surface and a clean white margin, particularly vibrant in the spring.

Cultivating Ganoderma tsugae is an advanced endeavor. It is ideally suited for dedicated outdoor growers, permaculturists, and homesteaders seeking to integrate natural fungi into their landscaping.

This process offers a rewarding challenge for those embracing self-sufficiency and ecological diversity in their outdoor projects.

Beyond its aesthetic appeal, Reishi mushrooms are widely recognized for their functional properties. Incorporating Hemlock Reishi into your outdoor environment can contribute to both natural beauty and potential wellness benefits.

North Spore’s commitment to scientific expertise and premium quality ensures successful inoculation. For optimal results and detailed guidance, explore our extensive online resources on log preparation and inoculation techniques.

Inoculation

Hemlock reishi mushroom grows on hemlock. It 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 hemlock 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.

Cultivation

Ideal project size: Plug spawn is ideal for smaller projects of 1-10 logs, though some log cultivators will use them for larger projects.

Storing

If you don't plan to use within 3 weeks, you may refrigerate the plug spawn for up to 6 months.

Cooking

The fresh, soft growth of the "lip" ofG. tsugae can be sautéed and prepared much like other edible mushrooms. However, the tough woody center is 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.

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.

• Aside from being kiln dried, our wooden dowels are not treated in any other way.

Frequently Asked Questions

After inoculation, most logs take 6–12 months before producing their first flush of mushrooms. Colonization depends on temperature, moisture, and wood type. Once established, a log can fruit for 3–7 years.

Always use freshly cut, disease-free logs. Old or rotting wood may contain competing fungi or be too dry for successful colonization. Ideally, inoculate within 2–4 weeks of cutting.

Plug spawn (wooden dowels) is easier for beginners and ideal for smaller projects. Sawdust spawn is faster to colonize and more economical for larger batches or commercial growers.

Store logs in a shady, humid area close to the ground. In dry or hot weather, occasional watering or soaking can help maintain moisture. Avoid full sun or windy spots, which can cause bark cracking.
