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 to 1.3–1.9 × 0.6–1.2 mm; rarely hemiisophyllous;

hyaline cells non-ornamented, nonseptate or sometimes septate.

lacking or short and slender.

± tapering, leaves loosely imbricate to spreading and often squarrose in shade forms.

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 elliptical, 1.5–2 × 0.9–1.6 mm;

hyaline cells on convex surface with elliptic to more often round pores along the commissures, comb-lamellae can be present, but often absent or restricted to leaf bases; chlorophyllous cells broadly triangular in transverse section and well-enclosed on the convex surface;

end wall not thickened.

dioicous.

dioicous.

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

with scattered pseudostomata.

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

proximal laesura less than 0.5 spore radius.

27–31 µm; granulate on both surfaces;

laesura on proximal surface less than 0.5 the spore radius.

fascicles none or 1 spreading branch.

fascicles with 2 spreading and 2–3 pendent branches.;

branch stems with cortical cell comb-lamellae weakly differentiated on interior wall, no or weak funnel-like projections on the interior end walls, pores in superficial wall mostly restricted to leaf attachments.
