Step 2: Substrate Needs for Tremella

how to grow tremella mushroom

Tremella mushrooms are parasitic on other fungi, typically requiring the presence of a host fungus such as Hypoxylon archeri for successful growth. The substrate preparation for Tremella, therefore, involves creating an environment that supports both the host fungus and the Tremella mushrooms.

Selecting the Base Substrate

The base substrate for Tremella cultivation is typically a lignocellulosic material such as sawdust, which provides the necessary nutrients for the host fungus. Broad-leaf sawdust is often preferred, and it can be supplemented with additional nutrients to enhance growth.

Supplementing the Substrate

Supplements such as wheat bran or rice bran are added to increase the nutritional value of the substrate. The typical supplementation ratio is around 10-20% of the total substrate volume. Other potential supplements include calcium carbonate and sucrose, which can be added in smaller amounts (around 1-2% each) to adjust the pH and provide additional carbohydrates for the fungi.

Composting the Substrate

While some mushrooms can be grown on non-composted substrates, composting can be beneficial for Tremella cultivation. Composting involves mixing and watering the ingredients, and then allowing them to ferment. This process can help break down the lignocellulosic materials, making them more accessible to the fungi.

Pasteurization or Sterilization

After composting, the substrate must be pasteurized or sterilized to eliminate any competing microorganisms. Pasteurization typically involves heating the substrate to 60°C (140°F) for 1 to 2 hours. If sterilization is required, the substrate should be heated to a higher temperature, such as 121°C (250°F), for a longer period, often 6 to 8 hours.

Adjusting pH Levels

The pH of the substrate should be adjusted to be slightly alkaline, around 7.5 or higher, to provide selectivity against contaminants like Trichoderma green mold. Limestone is commonly used to adjust the pH.

Incorporating the Host Fungus

For Tremella cultivation, the host fungus Hypoxylon archeri is introduced to the substrate using a dual culture technique. This involves inoculating the substrate with both the host fungus and the Tremella spawn, which can be done using mother spawn prepared with both fungi.

Bagging the Substrate

Once the substrate is prepared and inoculated, it is packed into plastic bags or containers. These bags should have holes punched in them to allow for gas exchange and are typically covered with a breathable fabric to prevent contamination.

Preparing the substrate for Tremella mushroom cultivation is a nuanced process that requires attention to detail. By selecting the appropriate base materials, supplementing with nutrients, composting, and ensuring proper pasteurization or sterilization, cultivators can create a conducive environment for both the host fungus and the Tremella mushrooms. Adjusting pH levels and incorporating the host fungus are also critical steps in the preparation process.

Step 3: Inoculation

Inoculation is the process of introducing spores or mycelium into a prepared substrate to initiate the growth of mushrooms. For Tremella mushrooms, this process is slightly more complex due to their parasitic nature, requiring a host fungus for successful cultivation.

Inoculating with the Host Fungus

1. Selecting the Host Fungus: Tremella fuciformis requires a host fungus, typically Hypoxylon archeri, for growth. The substrate should first be inoculated with the host fungus.

2. Dual Culture Technique: Utilize a dual culture technique by making mother spawn that includes both the host fungus and Tremella spores. This method enhances the ability of Tremella fuciformis to digest the substrate, thereby increasing yields.

Introduce Tremella Spores or Spawn

1. Mixing Spawn with Substrate: In a sterile environment, mix the Tremella spawn with the prepared and cooled substrate. If using spores, ensure they are evenly distributed throughout the substrate.

2. Packing: Fill the inoculated substrate into sterilized bags or containers. These should have small holes or filters to allow for air exchange while preventing contamination.

Incubation

  1. Ideal Conditions: Place the inoculated substrate in a dark, warm area with temperatures maintained between 20-25°C (68-77°F). This environment mimics the natural conditions under which Tremella mushrooms grow.
  2. Monitoring: Regularly check the substrate for signs of mycelial growth. The presence of white, web-like structures indicates successful colonization.

Tips for Successful Inoculation

  • Cleanliness: Maintain a sterile environment throughout the inoculation process to prevent contamination.
  • Temperature and Humidity: Monitor and control the temperature and humidity levels during the incubation period to ensure optimal growth conditions.
  • Patience: The colonization process can take several weeks. Patience is key as the mycelium establishes itself within the substrate.

Expanding on the fruiting process for Tremella mushrooms (Tremella fuciformis), also known as Snow Fungus, involves creating the right conditions to encourage the development of mushroom fruit bodies. Here’s a detailed guide based on the search results and additional insights:

Steps 4: Fruiting & Harvesting 

Create the ideal fruiting environment

1. Temperature and Humidity: Tremella mushrooms require a specific range of temperature and humidity to fruit. The ideal temperature is between 18-24°C (64-75°F), with a relative humidity of 85-90%.

2. Lighting: While Tremella mushrooms do not require as much light as some other mushroom species, they do need some indirect sunlight or fluorescent lighting to initiate fruiting. A light cycle of 12 hours on and 12 hours off is recommended.

3. Air Exchange: Proper ventilation is crucial for mushroom development. A fruiting chamber, such as a Shotgun Fruiting Chamber (SGFC), can provide the necessary air exchange while maintaining high humidity.

Monitoring and Adjusting Conditions

  1. Hygrometer: Use a hygrometer to monitor the humidity levels within the fruiting chamber and adjust as necessary.
  2. Misting and Fanning: Regular misting can help maintain humidity, while fanning several times a day can provide fresh air to support mushroom growth.

Recognizing the Signs of Fruiting

  1. Primordia Formation: The first signs of mushroom fruiting are small, knot-like formations called primordia. These will develop into mature fruit bodies.
  2. Pinset: As the primordia grow, they will develop into pinheads, which are the early stages of mushroom caps.

Harvesting the Mushrooms

Maturity: Tremella mushrooms are ready to harvest when they reach their full size and have a jelly-like consistency. They should be harvested before they begin to deteriorate.

Technique: Gently twist and pull the mushrooms from the substrate to harvest them. Avoid damaging the mycelium to allow for subsequent fruiting.

Tips for Successful Fruiting

  • Consistency: Maintain consistent environmental conditions within the fruiting chamber to avoid stressing the mycelium.
  • Cleanliness: Keep the fruiting area clean to prevent contamination and disease.
  • Patience: The fruiting process can take several weeks, so patience is essential as you wait for the mushrooms to develop.
