Black trumpet mushrooms (Craterellus cornucopioides), also known as the “horn of plenty” and “trumpet of the dead,” are funnel-shaped mushrooms that feature a brown, black, or gray color. These mushrooms are notable for their unique appearance, distinctive flavors, and culinary uses.

Black trumpet mushrooms have a hollow, fragile stem and thin, smooth flesh. They often grow in groups, forming small clusters of 3 to 6 mushrooms. The fruiting body can reach up to 3 ½ inches wide and between 1 and 5 ½ inches tall.

The unique flavor of black trumpet mushrooms lends itself well to a wide variety of dishes. Often described as having a rich, earthy, and slightly sweet taste that’s both fruity and aromatic, these mushrooms exhibit potent flavor when fresh.

Additionally, black trumpets are known for being excellent when dried, as their hollow structure allows them to maintain their texture and taste even after dehydration.

Black trumpet mushrooms are found in various regions worldwide, primarily in hardwood forests with mossy areas. They have a significant association with specific tree types and demonstrate a fascinating interaction with their environment.

North America

In North America, black trumpet mushrooms can be found on both the East and West Coasts. On the west coast, their growing season is during the winter months, from November until the beginning of March.

On the East Coast, however, black trumpet mushrooms grow during the summer, from mid-July until the end of August. They typically grow in hardwood forests and are often found near oak and beech trees, forming mycorrhizal relationships with the roots.


Black trumpet mushrooms are native to Europe and grow in similar habitats to North America. They are frequently found in clusters on the forest floor, near trees such as oaks and beeches. The mushrooms are well-suited for the climate and forest conditions found across the continent.


In the Midwest region of the United States, black trumpet mushrooms are less common but can still be found in appropriate habitats. Similar to other regions, they usually grow in or around hardwood forests, specifically near oak and beech trees or occasionally pines.

These mushrooms might also coexist with various other types, such as saprotrophic species like porcini.

Hunting Techniques

To successfully hunt Black Trumpet mushrooms, consider the following:

  • Season: On the West Coast of North America, they grow in the winter (from November to early March), whereas, on the East Coast, they can be found in the summer (from mid-July to late August)
  • Habitat: Black Trumpets usually grow in deciduous and mixed forests, often under beech, oak, or poplar trees.
  • Indicators: Look for moss or leaf litter, as Black Trumpets often grow close to the ground and can be harder to spot due to their dark color.

Harvesting Tips

When harvesting Black Trumpet mushrooms, it is important to:

  • Use scissors or a knife to cut the stem from the base. This ensures that the mycelium, the fungus’s main body, is not damaged.
  • Bring a basket or breathable bag for collecting the mushrooms, which helps preserve their delicate structure.
  • Be mindful of insects and other organisms that may be present on the mushrooms.

Cleaning Process

Proper cleaning is essential for Black Trumpet mushrooms to make the most of their unique flavor. Here is a recommended process:

  1. Remove any visible dirt or debris with a soft brush or your fingers.
  2. If needed, rinse the mushrooms briefly under water. Avoid soaking them, as this can affect their taste and texture.
  3. Slice the mushrooms lengthwise to ensure that no insects are hiding within the hollow stem.
  4. Lay the mushrooms on a clean, dry surface to allow them to air-dry before cooking or storing.

Black trumpet mushrooms are often used in gourmet dishes and can be found in various recipes whether they are enjoyed fresh or dehydrated. Take this Boeuf Bourguignon with Mashed Potatoes and Celeriac recipe for example.

To cook fresh mushrooms, simply wash them thoroughly, drain, and pat them dry. Dehydrated black trumpets can be rehydrated by soaking them in warm water or stock for about 20 minutes.

For a smoother texture and rich flavor, some cooks prefer to rehydrate them in white wine. It is important to avoid overcooking black trumpet mushrooms, as they can lose their distinct aroma and become rubbery in texture.

Sauteeing is a popular cooking technique for black trumpet mushrooms, as it helps to release their flavors and aroma.

They can also be added to a variety of dishes, such as soups, sauces, and stews. Additionally, these mushrooms pair well with wild game meats or can be used as a garnish for grilled or roasted vegetables.

Health Benefits

Black trumpet mushrooms are not only delicious, but they also offer some health benefits. These mushrooms are a good source of vitamins and minerals, such as vitamin C and antioxidants, which may help boost immune function.

One of the noteworthy health benefits of black trumpet mushrooms is their antioxidant content. They are rich in ergothioneine, which helps reduce damage caused by free radicals and oxidative stress.

In addition to their antioxidant properties, black trumpet mushrooms provide essential minerals like calcium. Calcium is crucial for maintaining strong bones, healthy teeth, and proper nerve and muscle function.
