|discussion=<p>Plants of <i>Pohlia obtusifolia</i> with sporophytes are generally small, but some sterile colonies in late snowmelt areas at high elevations form deeper cushions. When plants are sterile, the subtly cucullate leaves provide a clue to their identity; they are similar to those of <i>P. drummondii</i>, but the stems tend to be less red, the laminal cells are broader and thinner walled, and axillary gemmae are absent. <i>Pohlia obtusifolia</i> is paroicous (unlike <i>P. drummondii</i>, which is dioicous) and the capsules are barrel-shaped, with straight, rectangular walls (sinuate in <i>P. drummondii</i> and other gemmiferous species). The peristome of <i>P. obtusifolia</i> is relatively reduced, with slenderly triangular exostome teeth that are weakly pitted basally, a low endostomial basal membrane, and narrow segments that are weakly keeled but broadly perforate.</p>
