Oregon Black Truffle
Leucangium carthusianum, the Oregon black truffle, is a hypogeous (underground) ascomycete in the family Morchellaceae that is ectomycorrhizal with Douglas-fir in the Pacific Northwest. Its dark brown, rough to smooth fruit bodies can resemble lumps of coal, and the gray to brownish interior is divided into pockets by veins. Mature specimens have a pungent, fruity odour usually likened to pineapple.
Edible and valued; collected commercially, often with trained dogs. It is usually shaved raw over food for its musky aroma, and only mature specimens are aromatic. Confirm identification, since other truffle-like fungi grow in the same habitat.
Never eat a wild mushroom based on a web page — confirm with an expert.
Mycology is an evolving science: names, classifications and safety information change as research advances. Entries are compiled from cited sources and reviewed, but may be incomplete or out of date — check the sources, and never rely on this library alone to identify or eat a mushroom.
