🤍 White Beech Mushroom Spawn Guide (Hypsizygus tessulatus)

Ready to step up your mushroom growing game? The White Beech Mushroom (Hypsizygus tessulatus)—also known commercially as Bunapi-shimeji or the white clamshell mushroom—is an incredible gourmet edible!

Originally native to East Asia where they naturally grow on hardwood beech trees, this specific white variety is actually a unique UV-induced mutant of the wild-type brown beech mushroom (originating from Japan and originally registered by the Hokto Corporation). It produces absolutely stunning, tightly packed commercial clusters of small, thin, brilliant white mushrooms that are incredibly popular in Asian cuisine.

Please note: Beech mushrooms require a bit more patience than your standard oysters, as they need a much longer incubation period. They are also best grown on sterilized or super-pasteurized supplemented sawdust blocks only!

🌾 Recommended Substrates To get those famous, abundant clusters, this wood-loving strain requires a high-nutrient diet! We highly recommend:

• Master’s Mix (a 50/50 blend of hardwood sawdust and soy hull pellets)

• Hardwood sawdust heavily supplemented with nutrients (like oat bran, wheat bran, or soybean meal) at a rate of 10% to 30%.

🛠️ How to Prepare Your Substrate & Inoculate Because White Beech mushrooms thrive on highly nutritious supplemented substrates, standard hot-water pasteurization is not enough. You will need to treat this like an advanced grow!

• Hydration: Before processing, ensure your bulk substrate mixture is thoroughly wetted to a 60% moisture level.

• Sterilization is Key: Your supplemented substrate blocks should be fully sterilized in a pressure cooker at 15 PSI for 2.5 hours, or “super pasteurized” by steaming them at atmospheric pressure for 10 to 12 hours.

• Clean Inoculation: Because you are mixing your spawn into fully sterilized material, you must be extremely clean! Always inoculate your cooled blocks in front of a laminar flow hood or inside a Still Air Box (SAB) wiped down with 70% isopropyl alcohol.

🧫 Incubation (Colonizing Your Block) Once you have cleanly mixed your spawn into your prepared, sterile substrate and sealed your bags, it is time to let the mycelium take over!

• Temperature: Store your inoculated bags in a clean, dark space with stable temperatures between 16-20°C.

• Fresh Air: The growing mycelium needs to breathe! Ensure your incubation room has good ventilation, aiming for ideally one room air change per hour.

• The Golden Rule—Patience!: Beech mushrooms require a significantly longer incubation time compared to fast-moving Oysters. Even after the block looks fully white, it needs extra weeks to consolidate and mature before it is truly ready to fruit. Don’t rush it!

🌤️ Best Fruiting Environment White Beech mushrooms are top-fruiters! You will need to cut the top of the bag open to allow the clusters to grow straight up.

• Temperature: Once fully consolidated and ready to fruit, they require a cooler temperature drop to trigger pinning. Aim for a temperature range of 13-18°C.

• Light: Place your fully white block somewhere with enough natural, indirect light to read a book by. While they lack the pigment of the brown variety, they still need proper light to trigger healthy pin and cap development!

• Humidity: Keep it incredibly high (80-90%+). Because they fruit from the exposed top of the block, they need consistent environmental moisture to form healthy pinsets.

• Fresh Air: To get beautifully proportioned stems and caps, aim for high fresh air exchange (6-8+ room air changes per hour).

🍄 Tips & Harvesting

• Inoculation Rate: Because you are mixing your spawn into fully sterilized material in a highly clean environment, you only need an inoculation rate of 3% to 5% by weight. Your 1.7kg spawn bag will go a very long way!

• Fun Mycological Fact: This fungus is often confused with Hypsizygus ulmarius, the Elm Oyster! Interestingly, a radical alternative view based on recent ITS DNA barcoding suggests that all members of this genus might actually be the exact same species.

• When to pick: Harvest the entire bunch at once! The best time to pick is when the stems are elongated and the small white caps have slightly expanded but are still convex (dome-shaped). Gently twist and pull the entire cluster away from the block, then trim the base before tossing them into your favorite stir-fry or soup.
