Flora of North America species comparison

0.2–0.6 cm.

0.2–0.3 cm.

2–4 mm, when dry loosely sheathing at the base, the blade narrow, curved and often hooked at the tips, erect-spreading and almost straight when moist;

sheath oblong to oblong-ovate, in leaves near the base of the shoot abruptly contracted to the blade, in distal leaves more gradually tapering, not hyaline-margined, with a narrow strip of incrassate cells at the shoulders;

blade narrowly lanceolate to linear, slenderly acuminate, ending in a short point;

marginal lamina ± plane, variable in width, 1-stratose, irregularly notched-dentate or at times almost entire;

costa smooth or weakly toothed abaxially near the tip;

lamellae 11–16, entire in profile, 4–8 cells high, the marginal cells larger and rounded in section, single or in pairs, smooth;

sheath cells short-rectangular;

cells of lamina 10–12 µm, subquadrate to irregular.

1.5–3 mm, incurved at the tips when dry, erect-spreading when moist, gradually tapering to the blade;

sheath oblong, entire, not hyaline-margined, the zone of incrassate hinge-cells at the shoulders not sharply defined;

blade lanceolate, broadly and bluntly pointed, appearing turgid and fleshy, entire;

marginal lamina erect, narrow, 1-stratose;

costa ending in the tip, smooth abaxially;

lamellae 25–40, entire in profile, 7–12 cells high, the marginal cells in section rounded, often thicker-walled, smooth;

sheath cells short-rectangular;

cells on the abaxial surface of blade 14–17 µm wide, thick-walled, longitudinally elongate in the median portion, subquadrate to either side.

1–3.5 cm, reddish.

(0.5–)1.5–2.5 cm, reddish, often twisted below the capsule.

2.5–4 mm, erect or nearly so, sometimes indistinctly angled;

exothecium scabrous, the cells short-rectangular, thick-walled;

operculum obliquely rostrate;

peristome 190–220 µm, divided to 0.8.

2–2.5 mm, ± asymmetric, suberect to inclined to almost horizontal;

operculum with a convex base and a short, rather blunt beak;

exothecium mammillose, the cells short-rectangular, thick-walled;

peristome to 300 µm, deeply divided almost to the capsule rim, the teeth reddish with hyaline margins.

9–12 µm.

13–18 µm.
