Flora of North America species comparison

leaves triangular-lingulate to lingulate, 1.1–1.4 mm, apex broad-rounded to narrowly truncate, border very broad at base (more than 0.3 width);

hyaline cells efibrillose, rhombic, mostly 1-septate but can be non-septate.

leaves broadly ovate, 1.5–2(2.5) mm; straight;

hyaline cells fibrillose and nearly aporose, with single small pores occasionally found in the distal cell ends on the concave surface.

long and tapering, usually strongly 5-ranked.

lacking or short and slender.

ovate-lanceolate, 0.9–1.4 mm, concave, straight, apex involute;

hyaline cells on convex surface with very small ringed pores (less than 0.25 cell width) along commissures near apex, changing abruptly to large elliptical pores (0.4 cell width or more) basally, concave surface with large round pores in proximal margins and leaf base.

when present similar to stem leaves but smaller, 0.8–1.2 mm, hyaline cells fibrillose and mostly aporose, 1–6 irregularly round-shaped membrane gaps in some cells near apex on convex surface.

dioicous.

dioicous.

usually immersed in perichaetiale leaves, but may be slightly emergent, pseudostomata absent from capsule surface.

17–26 µm, finely papillose on both surfaces;

proximal laesura less than 0.5 spore radius.

29–41 µm, coarsely papillose on both surfaces, indistinct raised sculpture on distal surface;

proximal laesura less than 0.5 spore radius.

fascicles with 2 spreading and 1–2 pendent branches.
