Discussion
Imbribryum mildeanum is a small, inconspicuous boreal-montane species that has been found in Maine and subalpine-alpine areas in the West. This species has generally not been recognized by North America workers, but, following the sense of European authors, the species can be confirmed from several boreal to montane sites; it is probably more widespread than the few records indicate.
Selected References
None.
