Flora of North America species comparison

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.

leaves triangular-lingulate to broadly lingulate, 0.9–1.3 mm, apex broadly rounded to obtusely angled, border very strong and broad at base (more than 0.4 width);

hyaline cells rhombic, efibrillose, most 0–1-septate.

lacking or short and slender.

long, tapering, imbricate, not 5-ranked.

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.

ovate, 2–2.5 mm, concave, straight, apex involute;

hyaline cells on convex surface with elliptic pores along the commissures grading from moderate-sized pores near leaf apex to large pores at the base, concave surface with large round pores in proximal portions of leaf.

dioicous.

monoicous.

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

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

proximal laesura less than 0.5 spore radius.

23–31 µm, irregularly coarsely papillose on both surfaces;

proximal laesura less than or equal to 0.5 spore radius

fascicles none or 1 spreading branch.
