Matsutake mushrooms, also known as “pine mushrooms,” are a highly valued and sought-after species of edible mycorrhizal fungi native to Japan. In the United States, matsutake mushrooms can be found in various locations, including the Washington coast, Northern California, Idaho, and Oregon.
Keep reading to learn how these unique, pungent, woodsy mushrooms can be identified, used in cuisine, and found or grown.
Biology and Habitat
Characteristics
Matsutake mushrooms have distinct characteristics that make them easy to identify, such as:
- Whitish or slightly brownish caps that can reach up to 25 cm in diameter
- Fibrous stems that grow between 3 to 16 cm in length, and about 1 to 3 cm in thickness
- Close-set gills with a slightly decurrent attachment to the stem
- A spicy-aromatic odor which is highly prized in Japanese cuisine
It is important to note that Matsutake mushrooms belong to a species complex, which includes similar species such as Tricholoma murrillianum.
Habitat and Distribution
Matsutake mushrooms are primarily found in pine forests, where they often grow in association with certain pine species. They form ectomycorrhizal relationships in coniferous forests with trees from the Pinaceae family.
These mushrooms can be found in Asia, North America, and Northern Europe. In East Asia, they are especially revered, and their delicate scent is highly valued.
Threatened Species
Matsutake mushrooms and their habitats face several threats, including deforestation, which leads to the loss of suitable habitat for the growth and formation of necessary symbiotic relationships.
In addition, the spread of the pinewood nematode, which weakens and eventually kills the host trees, has been impacting the growth of the mushrooms. Climate change has also played a part in affecting the Matsutake mushroom’s natural distribution and growth patterns.
Culinary Use
In Japanese Cuisine
Matsutake mushrooms are highly valued in Japanese cuisine for their unique aroma and spicy flavor. One of the most popular dishes featuring this mushroom is Matsutake Gohan, a rice dish that showcases the mushroom’s flavor by combining it with seasoned rice.
Another popular way to enjoy matsutake mushrooms is by grilling them. Sliced thin and grilled with shoyu (soy sauce) and mirin, this cooking method enhances the mushroom’s natural flavors and allows its unique scent to shine through.
Matsutake can also be used in soups such as miso soup, where their distinct aroma complements the subtle flavors of the broth. Moreover, they can be incorporated into other traditional preparations such as sukiyaki, a Japanese hot pot dish featuring thinly sliced meat, vegetables, and mushrooms simmered in a flavorful broth.
In North American Cuisine
In North America, matsutake mushrooms are often utilized in dishes similar to other specialty mushrooms like truffles. Matsutake can be steamed, sautéed, seared, roasted, or grilled, and also used in clear broth dishes.
When incorporating matsutake mushrooms into North American cuisine, cutting the fibrous caps and stems into thick cubes, slices, or coins helps to retain their flavor and texture. Due to their rarity, expense, and distinctive taste, it is typical to keep the preparation of matsutake mushrooms simple.
Purchase and Storage
Fresh Matsutake
Fresh Matsutake mushrooms, also known as pine mushrooms, can be found at specialty grocery stores, Asian supermarkets, and farmers’ markets during their season, which typically runs from September to January.
When storing fresh Matsutake mushrooms:
- Refrigerate them immediately after purchasing or harvesting
- Store them in a paper bag or a container with a lid
- Keep the temperature between 34-38°F in the refrigerator

To store dried Matsutake mushrooms:
- Keep them in a cool, dry, and dark place
- Store them in an airtight container to prevent moisture absorption
- Pay attention to the expiration date on the packaging
Don’t forget that if you’re unable to find Matsutake mushrooms locally, you can always try searching for them in specialty stores and online retailers.
Foraging Techniques
Foraging for Matsutake mushrooms can be an enjoyable outdoor activity, especially in the Pacific Northwest and Idaho, where these mushrooms are often found. To improve your chances of success and to ensure you are foraging safely, follow these techniques:
First, educate yourself on the appearance and habitat of Matsutake mushrooms. They typically grow in dense forests and are known for their distinct pine and cinnamon-like aroma. Look for forests with pine trees, especially Lodgepole pines and Shasta red firs in the Pacific Northwest and Idaho.
When collecting mushrooms, use a basket or mesh bag to allow the mushroom spores to fall back to the forest floor, helping repopulate for next year. To harvest, gently twist the mushroom at the base or use a small knife, but avoid pulling it out of the ground to prevent damaging the mycelium.
Keep in mind these additional foraging tips:
- Always forage with a knowledgeable, experienced guide when starting out or consult a reputable field guide.
- Avoid collecting young, small specimens. This allows them to disperse spores and ensures a healthier mushroom population in the future.
- Be aware of the weather conditions, as Matsutake mushrooms are more likely to be found after heavy rain or during periods of high humidity.
Remember that foraging for wild mushrooms carries some risk, especially as the Matsutake mushroom resembles other toxic mushroom species.
Nutritional and Health Benefits
