Common in coniferous, mixed, or deciduous forests, open woodlands, conifer swamps, thickets, and old fields, usually on moist sandy acidic soils, often forming large clones. Resembling D. complanatum (treated as var. flabelliforme of that species in older books), but without the abrupt constriction at the base of branchlets. The branches fork into two diverging branchlets, producing a flat, dark green, regular fan-shaped pattern. The horizontal stem typically lies on the soil surface under a thin covering of leaf litter. The hybrid with D. tristachyum, named D. x habereri (House) Holub, is fairly common when both species grow together. It more closely resembles D. tristachyum, but the tip of the middle leaf on the lower side of the branchlets ends below the base of the leaf above it.
