Treatment appears in FNA Volume 27. Treatment on page 70. Mentioned on page 62.

Plants moderate-sized to large, moderately densely branched; green to brown, often bluish tinged and/or shiny when dry; capitulum flattopped with a conspicuous terminal bud. Stems dark-brown; superficial cortex of 2–4 layers of enlarged, thin-walled cells. Stem-leaves lingulate-spatulate, large, 1.3–1.6 mm; appressed to stem; apex very broad and lacerate; hyaline cells efibrillose and aporose, often septate. Branches strongly 5-ranked and straight. Branch fascicles with 2 spreading and 2 pendent branches, leaves not much elongated at distal end. Branch stems green, with cortex enlarged with retort cells. Branch leaves ovatelanceolate, 1.5–3 mm; straight to slightly subsecund; imbricate to somewhat reflexed and not undulate; margins entire; hyaline cells long and narrow, length to width ca. 10: 1 on convex surface with 1 or more small pores in the cell ends and angles and often with numerous pseudopores along the margins, on concave surface with large round wall-thinnings on the cell ends and angles; chlorophyllous cells triangular to trapezoidal in transverse-section, apex often exposed on concave surface. Sexual condition monoicous or dioicous. Spores 22–34 µm; both surfaces smooth, apparent ridged border on proximal surface; proximal laesura more than 0.5 spore radius.

Discussion

Sporophytes are uncommon. Sphagnum lindbergii is normally easily distinguished from other carpet-forming species of sect. Cuspidata by its large, strongly lacerate stem leaf and dark brown to black stem. Sexual condition is taken from from L. I. Savicz-Lubitzkaya and Z. N. Smirnova (1968).
