True Hypsizygus ulmarius — Know What You Are Buying

Elm Oyster is one of the most commonly mislabelled cultures on the market. Despite the name, it is not a Pleurotus at all — this culture is true Hypsizygus ulmarius, not Pleurotus ulmarius (sometimes sold as ElmA) and not Pleurotus ostreatus, which several suppliers list it as by mistake. It is also a different mushroom from Beech / Shimeji (Hypsizygus tessellatus), which shares the genus but not the species.

Why Choose Elm Oyster / White Elm Mushrooms?

• Attractive Broad Caps – Produces handsome cream, beige, or light tan caps with a classic gourmet mushroom appearance.
• Mild, Savory Flavor – Offers a delicate, pleasant taste that works well in a wide variety of recipes.
• Tender, Meaty Texture – Holds up nicely when sautéed, roasted, or incorporated into cooked dishes.
• Culinary Versatility – Excellent for stir-fries, soups, pasta, rice dishes, sauces, and sautéed recipes.
• Rewarding to Cultivate – A great option for growers looking to expand their collection with a distinctive edible mushroom.

Lab-Tested Liquid Culture for Reliable Growth

Our Grospore Elm Oyster / White Elm Liquid Culture Syringe contains vigorous living mycelium, lab-tested and prepared in our ISO-certified cleanroom to support healthy colonization and dependable cultivation performance.

Each 10ml (10cc) syringe offers:

• Live Mycelium, Not Spores – This is a liquid culture (LC) syringe, not a spore syringe. There is no germination step, so colonization begins as soon as you inoculate.
• Lab-Tested & ISO Cleanroom Prepared – Every batch is lab-tested for purity and prepared in an ISO-certified cleanroom, so what reaches you is clean, contaminant-free and viable.
• Faster Colonization – Active mycelium helps promote efficient colonization compared with starting from spores.
• Convenient 10ml (10cc) Syringe – 10cc and 10ml are the same volume. Easy to use with appropriately prepared sterile growing media, grain spawn or agar.
• Verified Genetics – Cloned, isolated Hypsizygus ulmarius mycelium — the true White Elm, correctly identified.

How to Grow Elm Oyster / White Elm Mushrooms

1. Prepare the Substrate – Hardwood sawdust-based substrates and other appropriately prepared lignocellulosic materials are commonly used for Elm Oyster cultivation. The same syringe can also be used to inoculate sterilized grain spawn, grain jars or bags, or an agar plate.
2. Inoculate – Inject 2–3cc (2–3ml) per grain jar or bag through a self-healing injection port, using sterile technique in a still air box or in front of a laminar flow hood.
3. Colonize – Allow the mycelium to fully colonize the substrate under suitable incubation conditions.
4. Initiate Fruiting – Once fully colonized, provide appropriate humidity, fresh-air exchange, indirect light, and suitable fruiting temperatures.
5. Harvest & Enjoy – Harvest while the caps are firm and well developed for the best texture and culinary quality.

Storage, Shelf Life & Shipping

Refrigerate your liquid culture syringe on arrival. Stored at 35–45°F (2–7°C), upright and out of direct light, it stays viable for 4–6 months. Orders ship fast from Oregon in discreet packaging, with tracking on every order and a 30-day return policy on unused items.
