Growing on the edge of a slow-moving stream in shade.
Classified as Sphagnum divinum because of color, shaded habitat, long divergent branch leaves that taper gradually, and spatulate stem leaves. The presence of large pores in the hyaline cells at the base of the branch leaves seems anomalous, more typical of Sphagnum medium. @janetwright @schneidried
