Yellow oyster mushroom – Pleurotus citrinopileatus
The yellow oyster mushroom, or Pleurotus citrinopileatus, is a mushroom native to Asia that is prized for its bright color, rapid growth, and relatively easy cultivation.
It has a delicate flavor, sometimes with a hint of fruitiness, and a more tender and delicate texture than that of the oyster mushroom.
Yellow oyster mushrooms are rich in protein, vitamins, and minerals. They also contain ergothioneine, a natural amino acid, as well as beta-glucans.
This tropical variety naturally bears fruit in mild to warm temperatures. It can tolerate slight drops in temperature, but performs best in a stable, humid, and bright environment.
Characteristics of the yellow oyster mushroom
- Origin: Asia
- Caps: generally 3 to 7 cm
- Color: bright yellow to pale yellow, depending on growing conditions
- Texture: tender, fine, and delicate
- Hardiness: a vigorous variety, generally less susceptible to disease
- Cultivation: particularly suitable when temperatures are mild or warm
🔬 This is mycelium on grains, intended for making your own growing media.
If you're just starting out, be sure to prepare your substrate properly, follow good inoculation practices, and maintain high humidity during fruiting.
❄️ Storing the mycelium: Store in the refrigerator, ideally between 1 and 4°C.
For best results, use it within one month of receipt.

Our Commitment to Quality
We produce our mycelium under laboratory conditions to ensure varietal purity and optimal quality.
Our mycelia are organically produced and certified BE-BIO-01 by Certisys under the Belgian Organic Agriculture program.
🌱 Growing conditions
The yellow oyster mushroom requires more heat than many other oyster mushrooms. It grows well at temperatures between 18 and 25°C, with good humidity and sufficient light to promote a beautiful yellow color.
Avoid drafts, sudden temperature changes, and letting the growing medium dry out. Regular ventilation is important for producing well-formed clusters.
Tip from La Mycosphère: To achieve a beautiful yellow color and well-developed caps, maintain high humidity at the start of fruiting, then ventilate regularly once the primordia appear.
🛠️ Recommended growing media
For indoor growing
Yellow oyster mushrooms grow well on pasteurized straw, pasteurized sawdust, and other lignocellulosic materials.
For a simple and consistent result, we recommend:
- Organic straw pellets: Add about 1 teaspoon of lime and 2 liters of cold water per kilogram of pellets.
- Sawdust-based substrate: suitable for wood-eating species and very convenient for regular cultivation.
📊 Growing conditions
Inoculation: 5 to 10% grain mycelium relative to the weight of the moist substrate.
| Phase | Temperature | Duration | Humidity | Light | CO₂ | Fresh air |
|---|---|---|---|---|---|---|
| Incubation | 20–28°C | 2–3 weeks | - | - | - | - |
| Formation of primordial cells | 15–25°C | 3–5 days | 95–100% | 500–1,000 lux | 500–1,000 ppm | 4 to 8 cubic feet per hour |
| fruiting | 18–25°C, ideally around 20–24°C | 3–5 days | 85–95% | 500–1,000 lux | 500–1,000 ppm | 4 to 8 cubic feet per hour |
📚 Estimated data from *Growing Gourmet and Medicinal Mushrooms* by Paul Stamets. Results may vary depending on the strain, substrate, humidity, ventilation, and growing conditions.
📈 Productivity
The yellow oyster mushroom is a high-yielding, fast-growing variety. On average, you can expect 200 to 250 grams of fresh mushrooms per kilogram of moist substrate, depending on the substrate and growing conditions.
FAQ – Yellow Oyster Mushroom
What is the ideal temperature for yellow oyster mushrooms?
Yellow oyster mushrooms thrive in mild to warm temperatures. For best results, aim for a temperature of 18–25°C during fruiting.
What type of growing medium should I use?
Pasteurized straw works very well, as does pasteurized wood shavings. Organic straw pellets are an easy way to get started.
Why do hats sometimes fade?
The color may vary depending on the light, temperature, and age of the mushrooms. Adequate light and harvest right stage help produce a beautiful yellow color.
How much does it produce?
On average, use 200 to 250 grams of fresh mushrooms per kilogram of moist substrate, with variations depending on the substrate and conditions.
What inoculation rate should be used?
We recommend using 5 to 10% grain mycelium relative to the weight of the moist substrate.
