Our Yellow Reishi is a first-generation Ganoderma curtisii isolate, a Reishi native to the southeastern United States rather than Asia. It forms kidney-shaped caps banded in gold and amber, and it's the rarest Ganoderma we carry.
A separate species from the Asian Red Reishi, found wild across the Southeast and rarely cultivated.
Kidney-shaped caps with yellow and amber bands instead of uniform red. No gills underneath.
Same substrate, temperatures and timing, so it's an easy add if you already grow G. lucidum.
Let the syringe reach room temperature, then shake it gently to break up and spread the mycelium through the broth.
Flame the needle until it glows, let it cool a few seconds, and wipe the injection port with the included alcohol pad.
Use 2–3cc per quart jar or 3–5cc per 3–5 lb grain bag. One 10cc syringe inoculates about 2–4 containers.
Keep it at 70–80°F in the dark. Shake once at about 30% colonization to speed things up.
Choose your shape: keep the bag sealed for branching antlers, or open and vent it for flat, banded caps. Same culture, same conditions; the air decides.
From our lab to your grainRun it into jars with wide-mouth cultivation lids or your own lids with self-healing injection ports. Spare 16G needles and sterile Luer Lock syringes are sold separately.
Use 2–3cc per quart grain jar and 3–5cc per 3–5 lb spawn bag. One 10cc Yellow Reishi syringe inoculates roughly two to four containers. Using more doesn't speed colonization much; it just uses up the syringe.
18–21 days at 70–80°F, then 25–35 days of fruiting. Plan on roughly two months from injection to harvest, with a long white-knuckle stage before the color comes in.
Supplemented hardwood sawdust indoors, or hardwood logs outdoors for growers willing to wait a season. Rye berries make good spawn. Like every Ganoderma, it won't perform on straw or manure.
They're separate species. Yellow Reishi (G. curtisii) is native to the southeastern US and has a kidney-shaped cap banded in yellow and amber. Red Reishi (G. lucidum) has a uniform deep-red lacquered surface. Growing conditions are effectively the same.
Refrigerate it at 35–45°F in the bag it shipped in and never freeze it; freezing ruptures the cells and kills the culture. Bring it to room temperature and shake gently before you inject.
Liquid culture is living mycelium from an isolated culture, so it skips germination, colonizes days faster and gives genetically consistent fruits. Spores have to germinate and pair up first, which is slower and more variable from grow to grow.
Liquid culture is living mycelium, so every syringe leaves our lab in a foil-lined insulated mailer. The insulation buffers it against summer heat in a delivery truck and against sub-freezing winter temperatures, so it arrives viable either way.
When it arrives: refrigerate the syringe at 35–45°F until you're ready to inoculate. Never freeze it. Bring it to room temperature and shake gently before use.
Sold as a mycological culture for cultivation. Yellow Reishi is the subject of ongoing scientific research, but nothing on this page is intended to diagnose, treat, cure or prevent any disease.
