Scientific Name

Kalapuya brunnea

Common Names

Oregon brown truffle


October – March


The truffle is reddish brown with a rough and warty outer skin, while the “flesh” is initially whitish before turning to a greyish-brown mottling as it matures. The “skin” or peridium has a texture similar to cartilage and breaks readily, which may affect the truffle appearance. Shape is roughly spherical, with lobes and furrows the size of a potato (12-60 mm in diameter). Fresh truffles are firm.


Mature truffles have an odor resembling garlicky cheese, similar to mature Camembert.


Found only in the wild of the the Pacific Northwest region of the United States (western Oregon and northern California).
