Sphagnum such gemmae. Peat moss can be distinguished from other moss species by its unique branch clusters. The plant and stem color, the shape of the branch and stem leaves, and the shape of the green cells are all characteristics used to identify peat moss to species. "Sphagnum" taxonomy has been very contentious since the early 1900s; most species require microscopic dissection to be identified. In the field, most "Sphagnum" species can be identified to one of four major sections of the genus—classification and descriptions follow Andrus 2007 (Flora North America): The reciprocal monophyly of these sections and two other minor
Sphagnum palustre light brown with stem diameters of 0.6 to 1.2 millimeters. The epidermis (Hyalodermis) of the stem is built in three layers and their cells form 1 to 3 seldom more pores and contain much spiral fibers. The branches are tufted forming clusters of three to six on the little stems. The heads are a little more pigmented and egg-shaped. "Sphagnum palustre" plants are spread across the whole of Europe and also can be found in parts of America, Australia and New Zealand. It is comparatively frequent and grows on moist and wet habitats like wet forests, often coniferous forests, on
