B.C., Asia (China, Japan, Korea).


Brotherella henonii suggests an overgrown version of B. canadensis, but is paler green, forms looser mats, and grows in more humid shaded sites. The penicillate rather than falcate-secund shoot and branch tips also easily distinguish B. henonii. The British Columbia populations from Queen Charlotte Islands are few, lack sporophytes, and are slightly different from much of Asiatic B. henonii, but this species is sufficiently variable to include the North American material.
