Plants green, yellow-green, brownish green to golden brown; branches straight to slightly curved. Stem leaves 1–1.4 mm, often spreading. Branch leaves 1.8–3.4 mm, straight to slightly subsecund; hyaline cells on convex surface with mostly 1 pore per fibril interval, pores more than 1/3 cell diameter. Spores 33–40 µm; distal surface finely and densely granulate.
Habitat: Habitat unclear due to recent taxonomic separation from subsp. majus, in North America, subsp. norvegicum seems to occur in weakly minerotrophic habitats such as poor sedge fens, lake edges, and floating mats
Elevation: low to moderate elevations
