Flora of North America species comparison

6–12(–20) cm, simple, densely matted with wooly whitish to light-brownish tomentum.

2–9 cm, simple, erect, in proximal part moderately to densely brownish tomentose.

2–5(–6) mm, erect to closely appressed when dry, erect-spreading when moist;

sheath oblong-rectangular, brownish, ± abruptly contracted to the blade;

blade narrowly lanceolate, acuminate, flat, with sharply infolded margins;

marginal lamina 6–7 cells wide, 1-stratose, entire to finely crenulate above, membranous and transparent, abruptly infolded and enclosing the lamellae and overlapping towards the apex;

costa toothed abaxially towards the apex, short-excurrent as a short, reddish brown awn;

lamellae bluntly crenate in profile, 5–8 cells high, the marginal cells in section pyriform, thick-walled, ending in a thickened knob, end cells of lateral lamellae ovoid and scarcely thickened at the apex;

sheath cells 45–80 × 7–10 µm, elongate-rectangular (5–7:1), narrower toward the margin;

cells of the marginal lamina transversely elongate, shorter and obliquely oriented towards the margins, very thick-walled and colorless.

3–8 mm, loosely imbricate, appressed to erect-spreading and flexuose when dry, patent to widely spreading and weakly recurved when moist;

sheath rectangular, scarcely narrowed to the blade;

blade lanceolate to linear-lanceolate, often caducous at the junction of sheath and blade, the apex subulate, weakly channeled;

marginal lamina 6–9 cells wide, distantly toothed to subentire;

costa excurrent as short brown entire to serrulate tip, smooth abaxially or with a few teeth near apex;

lamellae in profile entire to shallowly crenulate, 5–10 cells high, the marginal cells in section usually somewhat broadened, flat-topped or shallowly grooved, single or geminate, thin-walled, smooth, the marginal cells of lateral lamellae asymmetric;

median sheath cells 75–110 × 2–12 µm, linear;

cells of marginal lamina 9–15 µm, quadrate, thin- to firm-walled;

perichaetial leaves with long sheathing bases and short subulate blade.

2–4 cm, yellowish to reddish brown.

2.5–5 cm, reddish brown.

dioicous;

perichaetial leaves somewhat longer than the stem leaves, ending in a slender awn.

2–3 mm, short-rectangular to almost cubic (1–1.5:1), brownish, sharply 4-angled and prismatic, suberect, becoming horizontal when ripe;

peristome 200–230 µm, divided to 0.8, the teeth 64, obtuse.

2.5–3 cm, ± cubic, sharply 4–angled, suberect when mature, becoming horizontal when old;

peristome teeth 64, 160–210 µm, obtuse, the basal portion 60–75 µm.

dirty white to light brown, enclosing the capsule.

7–9(–15) µm.

12–15 µm.
