# Craterellus cornucopioides

Craterellus cornucopioides, or horn of plenty, is an edible mushroom found in North America and Eurasia. It is also known as the black chanterelle, black trumpet, trompette de la mort (French), trompeta de la mort (Catalan) or trumpet of the dead.

## Etymology

The Cornucopia, in Greek mythology, referred to the magnificent horn of the nymph Amalthea's goat (or of herself in goat form), that filled itself with whatever meat or drink its owner requested. It has become the symbol of plenty.
A possible origin for the name "trumpet of the dead" is that the growing mushrooms were seen as being played as trumpets by dead people under the ground.
It is one of several species that may be called djondjon in Haitian.

## Description

The fruiting body is shaped like a funnel expanded at the top, the stalk seamless with the cap, which is 0.5–7 centimetres (1⁄4–2+3⁄4 inches) in diameter. They grow up to about 10 cm (4 in) in height, exceptionally 15 cm (6 in). The upper and inner surface is black or dark grey, and rarely yellow. The lower and outer fertile surface is a much lighter shade of grey. The fertile surface is more or less smooth but may be somewhat wrinkled.
The size of the elliptical spores is in the range 10–17 μm × 6–11 μm. The basidia are two-spored.

### Similar species

Craterellus cornucopioides has a smooth spore-bearing surface, but the rare, distantly related Cantharellus cinereus has rudimentary gills. The colour and smooth undersurface make C. cornucopioides very distinctive.
The forms Craterellus fallax (with a different spore colour en masse) and C. konradii (with a yellowish fruiting body) have been defined as separate species, but DNA studies now show that the latter should be considered part of C. cornucopioides.

## Distribution and habitat

This fungus is found in woods in North America, Europe, East Asia, and Australia. In the American Pacific Northwest, it grows from November to March. It mainly grows under beech, oak or other broad-leaved trees, especially in moss in moist spots on heavy calcareous soil. In Europe it is generally common, but seems to be rare in some countries such as the Netherlands. It appears from June to November, and in the United Kingdom, from August to November. In Australia, they grow in rainforest gullies, often associated with Northofagus sp., appearing from January to May.
Because the mushroom tends to be blackish, it easily blends in with leaf litter on the forest floor. Some who hunt the species say it is like looking for black holes in the ground.

## Uses

Despite their unpalatable appearance, horns of plenty are edible and choice. According to a Portuguese study, 100 grams of dried C. cornucopioides contain 69.45 g of protein, 13.44 g of carbohydrates (mostly mannitol, a sugar alcohol) and 4.88 g of fat, amounting to 378 calories. They contain fatty acids, primarily of the polyunsaturated variety, as well as phenols, flavonoids and 87 mg of vitamin C. Along with Cantharellus cibarius (golden chanterelles) they are also a significant source of biologically active vitamin B12, containing 1.09–2.65 μg/100 g dry weight.
When dried, C. cornucopioides acquires black truffle notes; in this form it can be crumbled as a condiment.
