Description
This Pink Oyster liquid culture is a 10cc syringe of live Pleurotus djamor mycelium in a sterile nutrient broth, ready to inoculate grain or a prepared substrate. Pink Oyster is an edible gourmet mushroom known for its coral-pink color, tender texture and mild, slightly sweet, woody flavor. It likes warmer conditions than most oysters, which makes it a good choice for warm rooms and summer grows. The team at Atlas Spores prepares every batch in house in a clean room, tests it on agar, holds it until it shows clean and sterility-tests it before it ships.

About Pink Oyster
Pleurotus djamor grows in clusters of fan-shaped, coral-pink caps with a delicate, velvety texture. The pink color fades somewhat when the mushrooms are cooked, but the mild, slightly sweet, woody flavor stays, and the meaty texture holds up well to sautéing, roasting and grilling.
Growing Pink Oyster from Liquid Culture
- Substrate: Pink Oyster grows well on pasteurized or sterilized straw, sawdust, or a sawdust and bran blend.
- Inoculation: using sterile technique, inject 1–2ml of liquid culture into the prepared substrate, spreading the inoculation points evenly.
- Colonizing: keep the inoculated substrate warm (around 70–80°F), humid and out of direct light while the mycelium spreads over the next few weeks.
- Fruiting: once fully colonized, give fresh air, indirect light and 85–95% humidity at 65–85°F. Pink Oyster prefers the warmer end of that range, and clusters of pink caps form within days.
- Harvest: pick when the caps are fully expanded and the edges are just starting to curl, by twisting or cutting the cluster at the base.
Pink Oyster Compared with Our Other Gourmet Cultures
| Culture | Look and taste | Substrate | Fruiting temperature |
|---|---|---|---|
| Pink Oyster | Coral-pink clusters, tender, mild and slightly sweet | Straw, sawdust or sawdust and bran | Warm, 65–85°F |
| King Oyster | Thick, meaty stems, mild umami flavor | Hardwood sawdust with bran, or supplemented straw | Cooler, 60–70°F |
| Lion’s Mane | White cascading spines, mild and slightly sweet, texture often compared to crab | Sterilized hardwood sawdust or sawdust and bran | High humidity, 85–95% |
Quality and Testing
Every Pink Oyster batch is made in house at Atlas Spores. Media and tools are sterilized in an autoclave, and cultures are prepared under flow hoods in a clean room. Before a batch ships, samples are tested on agar and held until they show clean, and the batch is sterility-tested. Each syringe’s batch number and culture date are recorded against your order.
Frequently Asked Questions
How much Pink Oyster liquid culture should I use?
About 1–2ml per inoculation of a prepared substrate. One 10cc syringe covers several bags or jars.
What temperature does Pink Oyster need?
It colonizes best around 70–80°F and fruits at 65–85°F, preferring the warmer end. That makes it one of the better oysters for warm rooms and summer grows.
Does Pink Oyster keep its color when cooked?
The pink fades somewhat with cooking, but the flavor and texture don’t change.
How long does the culture last, and how should I store it?
Refrigerate it at 35–45°F and don’t freeze it. It is best used within 6 months and stays viable for up to 12 months refrigerated. Let it reach room temperature and shake it gently before use.
