Otherwise known as Horn of Plenty, is considered a great delicacy. This fragile, trumpet shaped Mushroom has a waxy, charcoal-gray outer surface, while the inside is a velvety blackish-brown. This is an incredibly rich and buttery Mushroom. This Mushroom can be found growing in large groups in damp deciduous woods, especially under oak or beech, during summer and fall. Black Trumpets work well as a flavoring ingredient in soups and casseroles. Black Trumpets are great in vegetarian cooking because they add a richness and depth that is often the role of meat in a recipe. These Mushrooms are delicious saute and added to rice dishes, particularly wild rice.
