Plants moderate to large-sized, dense and compact, pale green, brownish white, golden brown to variegated golden brown, can be reddish in rocky seep habitats; forms small, tufted compact cushions. Stems brown. Stem leaves small, 0.3–0.7 mm, triangular-lingulate with broad rounded apex, Branches short, crowded, and unranked. Branch fascicles 4–6 branches per fascicle, 2–3 spreading and 2–3 pendent, but plants frequently unbranched in young clones. Branch leaves large, 1.4–3 mm, semi-squarrose to squarrose, ovate and abruptly involute in distal portion, appearing cucullate with toothed apex, usually no more than 6 teeth; hyaline cells with 5 or more ringed, round to elliptical pores on convex surface, numerous pseudopores on concave surface with 3-ringed corner pores occurring in 3s at adjacent cell angles; chlorophyllous cells elliptic in transverse section, entirely included by hyaline cells, slightly nearer to convex surface. Sexual condition monoicous. Capsule with abundant pseudostomata. Spores 25–35 µm; finely papillose on proximal surface, coarsely papillose on distal surface with raised Y-mark sculpture; proximal laesura short, 0.3–0.5 spore radius.
Phenology: Capsules fairly common, mature summer.
Habitat: Ombrotrophic to weakly minerotrophic, commonly growing on poorly drained sand, siliceous rocks, bare peat
Elevation: low to high elevations

Discussion
Sphagnum compactum is usually easily recognized by its combination of golden brown color and involute, cucullate branch leaves. Sphagnum strictum is paler and usually strongly squarrose.
