Sphagnum capillifolium
Sphagnum capillifolium (= S. nemoreum) forms high, pinkish-red hummocks in oligotrophic habitats. The lanceolate stem leaves with some pores and fibrils identifies this species. Branch leaf features cannot be used to differentiate this species from S. fuscum, but S. capillifolium has clear (pinkish) stems.

| Habit | Small, green to pinkish-red plants with dense canopies, one pendent branch visible between capitulum arms; individual capitula hemispheric. |
| Stems | clear, with non-porose hyalodermis. |
| Leaves | ovate-lanceolate, minutely truncate at apex; stem leaves broadly lanceolate, with at least some fibrils and pores. |
| Leaf Cells | hyaline cells with large elliptic pores along the sides of the cell on convex surface, somewhat smaller, less conspicuous rounded pores in central part of cell on concave surface; green cells triangular, exposed on concave surface. |

| Habitat | Hummocks in bogs and peat plateaus; occasionally forming hummocks in both rich and poor fens. More abundant in eastern North America. |
| Common Associates | Usually few species occur intermixed with this species, but like S. fuscum occasionally mixed with Polytrichum strictum, Pohlia nutans, and Leiomylia anomala occur as scattered individuals. |
