Our Bioluminescent Panellus is a first-generation Panellus stipticus isolate, one of the few fungi on Earth that genuinely glows. The mycelium gives off a soft green light in full darkness, the old "foxfire" of glowing logs. It's a display and classroom culture, not a food crop: bitter and non-edible, though not poisonous.
A steady green light from living mycelium, visible in a dark room. Seeing it in person is the whole point.
Demonstrates bioluminescence directly, needs no special equipment and makes a standout science fair project.
The species is studied for breaking down organic pollutants and polyphenol waste, a second thread for older students.
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 port on your PF Tek jar with the alcohol pad.
Use 2–3cc per jar. One 10cc syringe starts about 3–4 jars.
Keep jars at 65–75°F in dim light. Once growth is established, take them into a fully dark room and give your eyes 5–10 minutes.
Set expectations: the glow is softer than photos suggest, more nightlight than lamp. Most glowing-fungus photos are long exposures. In a truly dark room, after your eyes adjust, it's still remarkable.
Set up your displayClear jars with wide-mouth cultivation lids let you watch the mycelium run and glow. Spare 16G needles and sterile Luer Lock syringes are sold separately.
Use 2–3cc per PF Tek jar. One 10cc syringe starts roughly three to four jars. Using more doesn't speed colonization much; it just uses up the syringe.
The mycelium glows as it colonizes, so you can often see light well before any fruit bodies form. In fruiting specimens it's strongest where the gills, cap and stem meet, and it intensifies as spores mature.
PF Tek jars. The glass lets you watch the mycelium run and see the glow without disturbing anything. Many growers never fruit it and simply keep the glowing jars as the finished display.
No. It isn't poisonous, but it's bitter and astringent, which is why it's called the bitter oyster. We sell it strictly as a display and educational culture.
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.
Haven't used it yet, but everything appears to be in order. Its a new species for me, so it'll be interesting to go through the process
I did not believe these mushrooms really would glow, had a couple extra bucks on my oyster order and grabbed one of these. Used one syringe for 2 Midwest grain jars. 50% colonized and they really glow! had to be really dark but it works!
