Identification Tips

Black trumpet mushrooms (Craterellus cornucopioides) are distinguished by their trumpet-shaped body and dark, often black coloring, which provides camouflage against the leaf litter. Foragers should look for:

• Color: Deep, dark gray to black

• Shape: Funnel-like with wavy edges

• Size: Typically 1-3.5 inches tall

• Texture: Smooth with a slightly wrinkled appearance

Note: Their lack of gills on the underside sets them apart from other mushroom species.

Hunting Locations

These mushrooms form a mycorrhizal relationship with certain hardwood trees, such as oak, beech, and ash. Key hunting locations include:

• Mossy areas: They often grow in damp, moss-covered regions.

• Slopes: The side of a hill or a slope can provide the necessary shade and drainage.

• Forest floor: While they grow in leaf litter, that same litter makes them harder to spot, requiring diligent searching.

Foragers should focus on shady spots where these trees are prevalent, especially during late summer to fall.

Gathering and Handling

When gathering black trumpets, gentle handling is crucial to preserve their delicate structure. Here's how to properly harvest:

1. Locate the mushroom and confirm identification.

2. Cut or pinch at the base to avoid disturbing the mycelium and surrounding soil.

3. Place gently in a basket or container with sufficient space to prevent crushing.

It's important to only take what can be used to encourage sustainability and future growth. They're best used fresh but can be dried for later use.

Safety and Preservation

When foraging wild black trumpet mushrooms, one must prioritize safety by accurately identifying the species and properly preserving them for later use. It’s essential to distinguish between true black trumpets and any lookalikes, clean and store the harvest carefully, and utilize effective drying techniques for long-term preservation.

Distinguishing from Lookalikes

Black trumpet mushrooms, known scientifically as Craterellus fallax or Craterellus cornucopioides, are generally safe for consumption, but foragers should be aware of the potential confusion with poisonous species. They feature distinctive false gills, which are shallow, forked, and vein-like, rather than true gills. There are very few lookalikes, but similarity to some inedible species like Craterellus cinereus or Craterellus foetidus may cause confusion; however, note that the differences lie mainly in the odor they emit. True black trumpets have a pleasant, fragrant smell, while the inedible Craterellus foetidus emits a rather unpleasant odor when close.

Cleaning and Storage

After harvesting, cleaning is crucial as black trumpets can harbor dirt and forest debris. Foragers should gently brush them or use scissors to trim the edges, ensuring minimal damage to the mushrooms. Before storage, ensure the mushrooms are free of any insects and debris. To store fresh black trumpet mushrooms, place them in a paper bag or wrap them in paper towels and refrigerate. This allows the mushrooms to breathe and maintain their texture and flavor for a few days.

Drying and Preservation

For long-term storage, drying is the best option for preserving the flavor and extending the shelf life of black trumpet mushrooms. Spread them out on a clean surface in a well-ventilated, dry area away from direct sunlight. A food dehydrator can also be used to achieve consistent results. Once dry, they should be brittle to the touch. Store the dried mushrooms (how long do dried mushrooms last?) in an airtight container in a cool, dark place. When ready to use, rehydrate them by soaking in water, which also allows them to regain much of their original size and texture.
