|discussion=<p><i>Pohlia atropurpurea</i> has sporophytes similar to those of <i>P. melanodon</i>, with dark reddish brown exostome teeth, yellow endostomes, and immersed stomata. This uncommon northern species is very small and soft, generally consisting of unbranched gametophytes that do not form extensive cushions. As in <i>P. melanodon</i>, the laminal cells are lax and thin-walled. Genetic relationships between this species and <i>P. melanodon</i> need study; <i>P. atropurpurea</i> could be a northern form of that species. Medial laminal cells of the perichaetial leaves are narrower than the broadly lax cells of proximal stem leaves. The exothecial cell walls of capsules of this species are somewhat collenchymatous.</p>
