The black trumpet, craterellus cornucopioide, grows in the European forests.
Black Trumpet (Craterllus Cornucopioides), a relative of the Chanterelle, and otherwise elegantly known as Horn of Plenty, is considered a great delicacy, being one of the most eagerly sought-after choice wild edible mushrooms. 
 
This fruity-fragrant, brittle fleshed mushroom is shaped like an inverted trumpet or vase, with a black to very dark gray cap about 2-7cm wide, a wavy irregular fringe at the margin that is frequently curved in when the mushroom is young, and a waxy, smooth to slightly rough or wrinkled charcoal-gray-black outer surface, with an interior of velvety black, fading in age to brown-black.
 
The dried black trumpet is an ideal side dish for duck or veal, and lends itself perfectly to the preparations with egg (omelet, scrambled eggs).
 
Rehydrate in water for 1-2 hours and rinse well.
