Overview

The black trumpet (Craterellus cornucopioides), also called horn of plenty or trumpet of the dead, is a thin, dark, funnel-shaped mushroom that hides superbly among fallen leaves — and rewards the forager who spots it with one of the richest, most fragrant flavours in the woods. A close relative of the chanterelle, it is mycorrhizal and cannot be cultivated, making every black trumpet a foraged prize.

Identification & Appearance

A hollow, trumpet- or funnel-shaped mushroom 3–12 cm tall, in dark grey, brown, or near-black, with a thin, wavy, brittle body. The outer surface is smooth or faintly wrinkled with no true gills. It is thin-fleshed and easily missed against dark leaf litter.

Where It Grows

Black trumpets grow in late summer and autumn in mycorrhizal partnership with hardwoods — especially oak and beech — on mossy or leaf-littered ground across temperate forests of the Northern Hemisphere, often in large scattered troops.

Foraging & Cultivation

Black trumpets cannot be cultivated — their root partnership with trees defeats farming. They are foraged, and because their dark colour camouflages them so well, finding the first one of a patch is the hard part; after that, many often appear nearby.

Growing Conditions

Light

Dappled woodland shade; black trumpets fruit on shaded forest floors among leaf litter.

Watering

They fruit in the damp of late summer and autumn, after rain.

Temperature & Substrate

A late-summer-to-autumn woodland species, growing only with living tree roots and not on any artificial substrate.

Culinary Use

Black trumpets have an intense, smoky, almost truffle-like aroma that concentrates beautifully when dried — many cooks consider them better dried than fresh, ground into a fragrant powder for sauces, pasta, and eggs. Fresh, they suit cream sauces and risotto. Cook them thoroughly.

Health & Nutrition

Low in calories, a source of fibre, B vitamins, and antioxidants. As with chanterelles, the value is culinary — flavour far outweighs nutritional standout.

⚠️ Safety note

Black trumpets have no deadly look-alikes, which makes them relatively forager-friendly, but as with all wild mushrooms, only eat them with expert confirmation and always cooked.

Pros & Cons

Pros

  • Intense, smoky, truffle-like aroma.
  • Dries superbly into a fragrant powder.
  • No deadly look-alikes.

Cons

  • Cannot be cultivated — foraged only.
  • Dark colour makes them hard to spot.
  • Thin-fleshed; quantity adds up slowly.

Best Suited For

  • Foragers who enjoy a rewarding hunt.
  • Cooks who want a deeply aromatic dried mushroom.

Not ideal for home growers — black trumpets cannot be farmed.

FAQ

Why is it called trumpet of the dead? Folklore — the dark trumpets appear around late autumn and were said to grow from the departed; it is harmless and choice.

Fresh or dried? Many cooks prefer black trumpets dried, as drying intensifies their smoky, truffle-like aroma.

Can I grow them? No — they are mycorrhizal and depend on living trees, so they are foraged in late summer and autumn.
