Wood ear mushrooms—the chewy, strangely textured fungi often seen in your favorite Asian dishes—are more than just interesting food. Also called wood ear fungus, they’re easy to grow, full of health benefits, and have an interesting botanical story. If you grow food in your backyard, are a skilled forager, or just love food, knowing how to grow wood ear mushrooms lets you have sustainable harvests and meals full of nutrients.
What Is a Wood Ear Mushroom?
Often called by its Latin name Auricularia, the wood ear mushroom is a jelly-like fungus that grows naturally on hardwood that is rotting, such as elder, oak, or beech. It is from forests in temperate and subtropical areas. It is named for its very close similarity to the human ear—thin, lobed, and pleated. Its most common kinds are:
- Auricularia auricula-judae – From Europe
- Auricularia americana – Common in North America
- Auricularia polytricha – Often grown in Asia
These mushrooms are a normal food in traditional Chinese cooking. They are valued not for their flavor—they don't taste like much—but for their uniquely crunchy, juicy texture. Their food value is in how they can soak up flavors around them like a sponge. This makes them great for soups with broth, salads with a kick, and stir-fries that sizzle.
Besides food, wood ear mushrooms are used as medicine. In Traditional Chinese Medicine (TCM), they are known to "cool down the blood" and "make dryness wet." People think they help blood flow, lower swelling, and lower cholesterol levels.
How to Identify Wood Ear Mushrooms
It is very important to correctly identify wild mushrooms, especially if you are foraging. Luckily, wood ear mushrooms have clear things that make them different from others:
| Feature | Description |
|---|---|
| Shape | Usually ear-shaped with thin, wavy edges. |
| Texture | Jelly-like or rubbery when fresh; becomes easy to break when dried. |
| Color | Ranges from dark brown to black or even reddish depending on type. |
| Spore Print | Clear white spore print helps make sure of the ID. |
| Growth Habitat | Likes hardwood trees that are rotting, like elder, beech, and oak. |
| Appearance | A little see-through when wet; may grow alone or in small groups that overlap. |
When you find them in nature, they often stick tight to the bottoms or parts without bark of logs and dead trees that are still standing. They can grow all year in wet places, but are most common when it is rainy in spring and fall.
Distinguishing Wood Ear Fungus From Lookalikes
Correct ID is important for taste and quality, but also very important for safety. One of the fungi most often confused is brown witch’s butter (Phaeotremella foliacea). This is another jelly-like mushroom that is found in similar places.
| Trait | Wood Ear (Auricularia spp.) | Brown Witch’s Butter (P. foliacea) |
|---|---|---|
| Color | Dark brown to black | Dark reddish-brown to amber |
| Texture | Rubbery, firm, a little see-through | Softer, jelly-like, less formed |
| Shape | Lobed, ear-like folds | Not regular, like brain clusters |
| Spore Print | White | Unknown, not as helpful for ID |
| Edibility | Edible and nutritious | Not poisonous but not usually eaten |
If you are a beginner forager, it's best to look at mycology field guides or get help from a mushroom ID group. Taking a spore print is a sure way to check. Put the mushroom gill-side down on a white sheet, cover it with a bowl, and check later after several hours. A bright white spore print usually means it is a wood ear.
How to Grow Wood Ear Mushrooms
Growing your own wood ear mushrooms can be rewarding and sustainable. It means you can always have this healthy food. Wood ears grow well on hardwoods or on prepared materials in a controlled place, unlike some other kinds.
What You’ll Need
What you need to grow mushrooms depends on the way you plan to grow them. It may include:
- Substrate: Hardwood logs (oak, beech, elder, maple) or sawdust that has been made better
- Spawn: Wood ear spores or mycelium grown to be sold
- Tools: Drill, hammer, rubber mallet, wax (to close up inoculation spots), gloves, tools to sterilize
- Environment: Wet, shady spot (greenhouse, shady garden, or indoor grow tent)
Wood ear mushrooms can change and adjust, making them great for people new to mushroom growing. Choose your substrate based on space, things you have, and weather.
Step 1: Prepare the Growing Medium
Using Logs
- Choose logs 3–6 inches across, cut from trees that are alive (best if cut within the last month).
- Good kinds are oak, elder, or maple. These woods are thick and give food for a long time.
- Put the logs fully in water for 24–48 hours to get them wet and ready to be colonized.
Using Sawdust
- Mix sterilized hardwood sawdust with about 10–20% wheat bran to make it richer in nutrients.
- Add a mild base, like lime (calcium carbonate), to make the pH balanced and help mycelial growth.
- Let the substrate sit for 3–5 days until the color gets darker and it smells like earth.
Step 2: Inoculation
Inoculation is putting the wood ear mushroom spores (spawn) into your prepared material:
- Logs: Drill holes 1–2 inches deep, spaced 6 inches apart in a diamond shape. Put in plugs or grain spawn, then close with cheese or beeswax to keep out pests and things that can contaminate.
- Sawdust Bag Method: Fill grow bags with the substrate, put in spawn, and close tightly. Some growers add a breathable filter patch or slit so air can get in and out.
Tip: Always sterilize your tools and wear gloves to make sure you don't contaminate.
Step 3: Incubation (Colonization Phase)
This is the time of waiting as the mycelium starts to colonize the substrate.
- Logs should be stacked in a shady place outside with good air flow and not directly rained on. If needed, cover with burlap or shade cloth.
- Grow bags should be put in a room inside or greenhouse where the temperature stays between 60–75°F (15–24°C) and the wetness stays around 85%.
Timeline:
- Logs: 6 to 12 months
- Sawdust: 4 to 8 weeks
White or gray webbing on the surface means colonization is working.
Step 4: Fruiting and Harvesting
Once the substrate is fully colonized, it’s ready to fruit. Make fruiting start by changing the environment, such as:
- Moisture shock: Soak logs for 12–24 hours or mist substrate bags a lot.
- Light cycle: Allow low-level, not direct daylight (12 hours on/off).
- Ventilation: Make airflow better to lower CO2 buildup and help pinning (baby mushrooms).
Mushrooms are ready to harvest when they are 2–4 inches across and feel bouncy and wet.
Common Challenges in Growing Wood Ear Mushrooms
Here’s how to fix common problems when growing:
| Challenge | Issue | Recommended Fix |
|---|---|---|
| Substrate contamination | Other fungi or bacteria growing on surface | Sterilize substrate well; don't water too much |
| Stalled colonization | Mycelium growth slow or not happening | Check temperature, change pH, make sure spawn is good |
| Patchy fruiting | Mushrooms not growing evenly | Mist evenly, turn logs or bags so all sides are same |
| Pests and mold | Green molds or gnats that can be seen | Remove parts that are contaminated; make airflow better |
| Fragile mushrooms | Mushrooms getting smaller too soon | Make wetness higher; harvest when fully wet |
Growing mushrooms needs you to watch and change the environment. Being patient is key.
How to Harvest and Store Wood Ear Mushrooms
Harvesting Tips
- Harvest in the early morning or after misting/rain when bodies are swollen and fresh.
- Use sterile scissors or a sharp knife to cut fungi off the log or bag. Don't pull hard so you don't hurt mycelium.
- Be gentle. Wood ears get bruised easily and can lose firmness if handled roughly.
Storage Options
| Storage Method | Instructions | Duration |
|---|---|---|
| Refrigerate | Put in a paper bag in fridge crisper | Up to 7 days |
| Drying | Dry slices until completely dry | 6–12 months in jar |
| Freezing | Quickly boil then freeze portions | 2–3 months |
For storage that lasts a long time, drying is best. Put in warm water again for 30 minutes before using.
Recipes and Culinary Uses
