Are you intrigued by the horn of plenty mushroom, also known as Craterellus cornucopioides or the “trumpet of death”?
Then landing on this page is no coincidence: you’re right where you need to be 😉
This post will walk you through how to distinguish this mysterious black mushroom from horn of plenty mushroom look alikes.
We’ll cover when and where to forage for it, horn of plenty health benefits and some delicious horn of plenty recipes.
If you’ve been meaning to get familiar with the horn of plenty fungi, this is your perfect starting point.
Horn of plenty name origin
Scientific name: Craterellus cornucopioides
Common names: Horn of plenty, black trumpet, trumpet of the dead, black chanterelle
The genus name Craterellus comes from the Greek word krater (meaning “cup” or “bowl”) combined with the diminutive suffix -ellus, giving us “little cup” or “small bowl”—a reference to the funnel shape of the mushroom.
The species name cornucopioides draws from the Latin cornucopia, meaning “horn of plenty”—another reference to the shape.
According to one version of the myth, the infant god Zeus was hidden from his father Cronos, who swallowed his newborn sons to prevent a prophecy that one of his sons would overthrow him.
Zeus was secretly nursed by the goat-goddess Amalthea. During play, he broke off one of her horns, which took on her divine powers. The horn—now called the Cornucopia—could endlessly provide food and drink1.
Distribution
The horn of plenty is quite localised in Britain and Ireland, but where it appears, it can grow in large numbers.
Although once thought to be a single species found across the globe, what was long grouped under Craterellus cornucopioides is now understood as a complex of closely related species2.
The true Craterellus cornucopioides (in the strict sense) is now considered native to Europe only—from Scandinavia down to the Mediterranean.
A very similar lookalike, Craterellus fallax, grows widely across North America, while other related species are found in Central and South America, Asia, and Japan.
Horn of plenty health benefits
Black trumpet mushrooms (Craterellus cornucopioides) aren’t just a gourmet delicacy—they’re also gaining attention as a “functional fungi”, a term used for mushrooms with potential health and nutritional benefits.
Though not as heavily researched as some of their better-known cousins like reishi or lion’s mane, early studies suggest these humble-looking mushrooms may be worth paying attention to.
From a nutritional standpoint, dried horns of plenty are surprisingly rich: in a 100g portion, you’ll find around 69g of protein, 13g of carbohydrates, and about 5g of fat. The rest includes fibre, minerals (ash), and a range of bioactive compounds.
Among those compounds are fatty acids, flavonoids, and phenolic substances—many of which are known for their antioxidant, anti-inflammatory, and immune-modulating effects.
The antioxidant power of black trumpets is primarily credited to their phenolic content, which researchers believe could support the body in managing chronic and degenerative conditions like cancer, heart disease, and even cognitive decline.
The fatty acids present may also play a role in reducing inflammation, with potential benefits for conditions such as asthma, diabetes, and obesity.
Some studies even suggest that these anti-inflammatory properties might help protect against neurological diseases like Alzheimer’s and Parkinson’s3.
Horn of plenty mushroom foraging tips
Horn of plenty mushrooms can be tricky to spot due to their dark, funnel-like shape that blends into the forest floor.
One handy tip: they often grow in the same habitats as chanterelles and near sphagnum moss. If you find mossy ground, slow down and look carefully—especially under leaf litter and among tree roots.
Key Identifiers of Horn of Plenty (Craterellus cornucopioides)
Overall appearance
The horn of plenty is a dark, hollow, trumpet-shaped mushroom that blends well into leaf litter and woodland debris, making it easy to overlook if not searching carefully.
Cap
The cap is funnel- or trumpet-shaped, featuring a wavy, rolled-in margin. Its diameter usually ranges from 4 to 8 centimetres, though it can grow up to 15 centimetres under ideal conditions. The upper surface, which is infertile, varies in colour from dark grey to black, occasionally showing brown or silvery-grey tones. Near the edges, the cap often displays wrinkled striations.
Stem
The stem is hollow all the way to the base and is often difficult to tell apart from the cap since they seamlessly join. Its colour ranges from ash grey to brown, with a finely wrinkled, powdery (pruinose) texture. The stem tapers slightly toward the bottom.
Flesh
The flesh is thin, fibrous, and grey to black in colour. It is quite fragile and can easily tear.
Gills/underside
Rather than true gills, the Horn of Plenty has a smooth to finely wrinkled fertile surface with faint ridges that run down the stem. This underside is pale grey to greyish-brown.
Spore print
The spore print colour varies from white to cream and may sometimes have salmon or yellowish tones.
Size
The mushroom typically grows between 5 and 10 centimetres tall, occasionally reaching 15 centimetres.
Odour and taste
Descriptions of smell and taste vary widely. Some find the aroma indistinct, while others describe it as sweet, fragrant, and strongly mushroomy. When cooked, especially dried, its flavour is considered excellent.
Horn of plenty lookalikes
The Horn of Plenty has no close lookalikes that match its distinctive dark, funnel-shaped appearance.
A few mushrooms share a similar overall form but differ noticeably in colour. For example, the chanterelle mushroom (Cantharellus cibarius), is bright yellow or yellow-orange and similar in size but easy to distinguish by its vibrant colour.
Another relative, the winter chanterelle (Craterellus tubaeformis), has a brownish cap paired with a yellow stem, making it quite different from the uniformly dark horn of plenty.
From a distance, the black elfin saddle (Helvella lacunosa) might appear somewhat similar, but its shape and texture set it apart upon closer inspection.
Habitat and ecology
The elusive horn of plenty mushroom (Craterellus cornucopioides) thrives in deciduous woodlands, especially beneath beech and oak trees. It favours calcareous soil and tends to appear in mossy patches.
Typically mycorrhizal with hardwoods—though it occasionally partners with conifers—it grows either scattered, in small groups, or more commonly in dense clusters.
Horn of plenty sustainability
Though not commonly encountered, the horn of plenty often appears in large clusters when it does emerge. Hidden well among leaf litter, it can be tricky to spot at first—but once you find one, you may be in for a rewarding harvest.
When to harvest
You can find horn of plenty mushrooms from June through November, sometimes even into December during mild autumns—especially in southern parts of Britain. They often persist well into the early winter months.
Culinary notes
Craterellus cornucopioides—also known as “poor man’s truffle”—might not win any beauty contests, but its flavour more than makes up for it.
Rich, earthy, and slightly fruity with hints of apricot and stone fruit, they bring a unique depth to any dish.
There’s a subtle bitterness on the finish that adds intrigue, which some foragers come to crave—just be careful not to overdo it by using too many mushrooms, especially in reductions or purees, as that bitterness can concentrate.
Horn of plenty mushrooms are hollow and cook quickly, so avoid overcooking. A large pile will shrink dramatically in the pan.
When fresh, they may also darken other ingredients they touch, turning them grey or black—a quirk to keep in mind depending on your dish.
Despite their delicate look, black trumpets are surprisingly robust. Their tough skin makes them resistant to maggot infestation, and they dry beautifully—just spread them out over a radiator or pop them in a warm oven with the door ajar. Once dried, store in airtight jars and they’ll last for months.
You can also cook them down into a rich sauce and freeze portions for easy winter meals—just label your bags or tubs.
Finely chopped, horn of plenty mushrooms make a decent visual stand-in for truffles, and a few raw slivers can even work as a garnish.
But go easy at first—they’re potent, and too many can overpower a dish.
Horn of plenty recipes
1. Creamy horn of plenty pasta
Sauté a handful of fresh or rehydrated dried horn of plenty mushrooms in butter or olive oil with garlic and shallots. Once soft and fragrant, stir in a splash of white wine and let it reduce. Add a swirl of cream, season with salt, pepper, and a pinch of thyme, then toss through cooked tagliatelle or linguine. Finish with fresh parsley and a sprinkle of grated hard cheese or a vegan alternative.
2. Mushroom & chestnut risotto
Rehydrate a small bowl of dried black trumpets in hot water, then chop roughly. In a pan, sauté onion in olive oil until soft, then add arborio rice and toast for a few minutes. Gradually add veg stock, stirring often. Stir in the mushrooms (plus the soaking water, strained), chopped cooked chestnuts, and a knob of butter or vegan alternative at the end for creaminess. Season well and serve with a drizzle of truffle oil if you like.
3. Wild mushroom toast
Toast thick slices of sourdough or rustic bread. While that’s toasting, fry your horn of plenty mushrooms in olive oil with a little garlic and thyme. Add a splash of soy sauce or tamari for depth. Pile the mushrooms on your toast and finish with cracked black pepper and a few rocket leaves. For extra richness, spread the toast with a thin layer of cashew cream or soft cheese first.
4. Horn of plenty salt
Dry the mushrooms completely (if they aren’t already), then blitz in a blender or spice grinder until powdered. Mix with sea salt and store in a jar. Use this umami-packed seasoning to sprinkle over roasted veg, popcorn, homemade chips, or even scrambled tofu. It’s a great way to stretch a small harvest and add deep, savoury flavour to everyday meals.
5. Black trumpet mushroom gravy
Soak a handful of dried mushrooms in hot water. In a saucepan, sauté chopped onion and garlic until golden. Add the rehydrated mushrooms (reserving the soaking water), a spoonful of flour, and stir to form a roux. Slowly whisk in the soaking water and a splash of tamari or soy sauce, then simmer until thickened. This earthy, rich gravy is perfect over mashed potatoes, nut roast, or even Sunday veg pies.
