Grow distinctive Grospore Antler Reishi with our lab-tested 10ml (10cc) liquid culture syringe. Also sold as deer antler reishi or branched reishi, this is the antler form of Ganoderma — grown under high CO₂, not the flat conk. Live mycelium, not spores.
Explore the fascinating world of Antler Reishi with our premium Grospore 10ml (10cc) liquid culture syringe. Known for its unique branching, antler-like formations and deep reddish-brown coloration, Reishi is one of the most recognizable functional mushrooms cultivated by mushroom enthusiasts. It is sold across the market as Antler Reishi, deer antler reishi, branched reishi and lingzhi, and listed variously as Ganoderma multipileum, Ganoderma lucidum and Ganoderma lingzhi — suppliers genuinely disagree on the name.
Our vigorous liquid culture provides active, healthy mycelium designed for reliable colonization and consistent performance, making it suitable for both newer growers and experienced mushroom cultivators.
This is the single most common point of confusion with reishi, so it is worth stating plainly: antler reishi and the flat, kidney-shaped conk are the same organism, and the form you get is a cultivation variable rather than a genetic one. Antler formations are encouraged by sealing the growing environment and letting CO₂ build up while limiting fresh-air exchange. Open the bag and increase fresh-air exchange, and the same culture will produce classic laccate conks instead. If you want antlers, keep the FAE low.
Our Grospore Antler Reishi 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:
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.
Antler Reishi offers a completely different cultivation experience from traditional cap-and-stem mushrooms. Its sculptural growth patterns, deep coloration, and functional-mushroom heritage make it an excellent choice for anyone looking to expand their mushroom collection.
Whether you are exploring mushroom biology, experimenting with different fruiting forms, or cultivating functional mushroom varieties, Antler Reishi provides a rewarding and visually impressive project.
Add one of the mushroom world’s most distinctive varieties to your collection with our Grospore Antler Reishi Mushroom Liquid Culture Syringe. Each 10ml (10cc) syringe contains lab-tested, vigorous living mycelium ready for your next cultivation project.

This is a reorder for me after the first syringe performed as expected on grain. I like having a second one on hand because the culture has been consistent, stores well in the fridge, and saves me time.

Placed my order late in the week and still got tracking almost right away, which honestly made my day. The package moved faster than I expected and showed up in great shape without any shipping drama. For something I wanted refrigerated quickly, that matters a lot. I have ordered hobby supplies from plenty of places that crawl through transit, so this felt refreshingly efficient and well handled from start to finish.
Graham, UT –
Put this to grain and it took off faster than I did after saying, “I’ll just check the jars once.” Colonization was thick and even, with no mystery colors or sad stalled spots. When I kept fresh air low, the fruits really did push those weird antler shapes instead of flat conks. Nice to have a culture that behaves like it read the instructions, even if I occasionally do not.

Reordered this after the first syringe performed as expected on hardwood mix. I wanted the same genetics again, not a substitute. Second order looked equally clean, stored well in the fridge, and gave me the consistency I was trying to keep.
Travis Cole –
Left this in the fridge for about six weeks before I got around to using it. Honestly expected it to be tired by then, but it still looked clean and kicked off growth just fine.
P.H. –
Before ordering, I reached out to customer service because the naming on reishi can get confusing fast, and I did not want to buy one thing and get another. I assumed I would get a vague canned reply. Instead, they answered plainly and explained that the antler form versus conk form comes down to growing conditions, not a different culture entirely. I sent a follow-up question about storage and whether I needed to use it immediately, and they replied with actual temperature guidance instead of generic advice. That changed my mind. The syringe itself looked healthy and performed fine, but what sold me was getting straight answers without any runaround. I started this purchase pretty doubtful, mostly because mushroom listings online can be sloppy. In this case, support was the part that felt most reliable.

What stood out to me was how fast this got here and how securely it was packed. Syringe was intact, clearly marked, and still cool when delivered. I used it on supplemented sawdust after expanding to grain and got strong white growth without any weird smells or stalls. Also appreciated that the listing explained the antler shape is about airflow, because that answered a question I had before I even started.
Curtis –
Strong growth on grain, no contamination, and the antler form showed well.

Got this for my brother after he had good luck with the first syringe, and he asked me to reorder the same one instead of trying something new. That alone made the gift choice pretty easy the second time.
Marta Solberg –
Bought one syringe to try this out on grain and ended up coming back for another after seeing how lively it looked and how smoothly the first run started. I like keeping a reishi culture around, and this one earned a permanent spot in the fridge rotation. Reordering was easy, the second syringe arrived just as clean-looking as the first, and consistency matters a lot to me.
Gordon Pike –
After my last try stalled, I was nervous, but this one looked cleaner and started faster.
Dustin Merrill –
From a value standpoint, I look at usable volume, visible mycelium density, and how far one syringe stretches. This gave me enough for multiple inoculations without looking watered down, so the cost felt justified rather than inflated.
Ayoa Quispe –
Ran this on supplemented sawdust after getting grain established first. What stood out was how strongly it favored antler growth once I kept fresh air low. For a classroom demo on growth form and environment, it made the point better than slides ever could. Clean start, steady colonization, and the fruiting bodies held up well after drying for display. Not the fastest project in my tent, but definitely one of the more interesting ones.
Ioan T. –
Figured the antler thing might be hype, especially with all the naming confusion around reishi. Ended up with dense white growth and, once I kept fresh air low, the fruiting really did push into antler shapes.
