Distribution
''T. murrillianum'' is found predominantly in the Pacific Northwest of the United States and Canada. It was previously included with the American matsutake, ''T. magnivelare'', but in 2017 scholarship based on molecular analysis separated the two and determined that ''T. magnivelare'' is limited to the eastern half of North America. In southern North America, the Mexican matsutake, ''T. mesoamericanum'', is found instead.The Western matsutake can be distinguished from its Asian counterparts by its whiter color, and from its North American counterparts by range, which does not overlap. It is mostly white while ''T. magnivelare'' and ''T. mesoamericanum'' tend to be darker in cap coloration, though all three can stain reddish brown with handling when mature. ''T. murrillianum'' also has a smoother pileus than the eastern ''T. magnivelare''.
