Black Trumpet
Craterellus cornucopioides
A thin, charcoal-gray trumpet that vanishes into leaf litter. Hard to spot, easy to identify once you do. Smoky and rich, and it dries beautifully.
The Short Answer
May add rich flavor and nutrients to meals; health effects untested in people.
A safe, smoky-tasting wild mushroom with no dangerous lookalikes, though it is hard to spot on the forest floor. Health claims so far are from lab and mouse studies.

Lab and animal studies
How to Eat It
Fresh, Cooked
Split lengthwise to wash out grit, then saute until tender.
Dried
Crumble into sauces or soak in warm water for 15 minutes before cooking.
A Normal Serving
A normal serving is about 1 cup cooked fresh (roughly 50 to 75 g), or a small handful dried. Try a small portion the first time.
If It Disagrees with You
A food sensitivity usually shows within a few hours as an upset stomach. No human studies track reactions over time.
⚠ Who Should Skip It
- Anyone without a 100% sure ID.
- People with a known mushroom allergy.
- Pregnant or breastfeeding people should skip wild-picked mushrooms.
- Mushrooms from polluted ground or roadsides.
How to Identify It
1
Hollow Trumpet Shape
A thin, dark gray to black funnel that is hollow all the way down, like a small horn.
2
Smooth Underside
The outside is smooth or faintly wrinkled, with no gills, pores or teeth.

What It Gets Confused With
Other dark cup or funnel fungi; if it has true gills or is not hollow, it is not a black trumpet.

The Research in Plain English
2018 · Black trumpet polysaccharide · Lab study
Researchers described a new sugar compound (polysaccharide) from the mushroom and found antioxidant activity in lab tests. No human data. Read the study ↗
2022 · Polysaccharide extract · Animal study
In mice, a polysaccharide extract from black trumpet appeared to support immune activity. Animal results often do not carry over to people. Read the study ↗
2020 · Digestion model · Lab study
Tested how black trumpet polysaccharides hold up in simulated digestion and gut bacteria fermentation. It suggests they reach the gut, but this was a lab model only. Read the study ↗
