Flora of North America species comparison

leaves shorter than branch leaves, 0.8–1.6 mm, lingulate, hyaline cells non-septate above and commonly 1-septate below.

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.

short and blunt, branch leaves imbricate.

lacking or short and slender.

0.9–2 mm, ovate, with conspicuously truncate apex, hyaline cells bulging on both surfaces, with 1–4 large circular to elliptic pores per cell on convex surface and 4–7 elliptic pores per cell on concave surface, internal commissural walls faintly papillose, cholrophyll cells elliptical to elliptical-ovate withn the broadest part typically some distance from convex surface.

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.

unknown.

dioicous.

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.

fascicles typically with 2 spreading and 2 hanging branches.;

branch stems with single layer of cortical cells.

fascicles none or 1 spreading branch.
