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 spatulate to broad-spatulate, 0.8–1.5(–2) mm, strongly lacerate across the broad apex and often part way down the margins, border scarcely to strongly broadened at base (0.25 width of base or less);

hyaline cells rhomboid, efibrillose and often 1–2-septate.

lacking or short and slender.

not 5-ranked, quite terete, long, and slender Branch fascicles with 1– 2 spreading and 1–2 pendent branches.

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 to ovate-lanceolate; 1.1–1.5(–2) mm, slightly concave, straight;

apex involute;

margins entire;

hyaline cells on convex surface with numerous pores along the commissures grading from small pores near leaf apex to large pores at base, concave surface with large round pores at leaf apex and along margins.

dioicous.

often 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.

20–27 µm, finely papillose on both surfaces;

proximal laesura less than 0.5 spore radius.

fascicles none or 1 spreading branch.
