Discussion
Pohlia beringiensis has cherry red stems with erect, whitish leaves and red bulbiform axillary gemmae. The gemmae are much like those of P. drummondii, but are even more red and contrast conspicuously with the whitish leaves. The organic-poor substrates on which P. beringiensis occurs are quite different from the relatively humic soils on which P. drummondii occurs.
