Flora of North America species comparison

1.5–3(–6) cm high, usually unbranched, sparsely radiculose at or near the base.

1–3(–6) cm, simple, erect or decumbent, the cortical cells thin- or thick-walled.

6–10 mm, erect and loosely appressed with recurved tips when dry, spreading and broadly recurved when moist;

sheath ovoid, hyaline-margined, golden brown, contracted to the blade, the cells at the shoulders forming a differentiated hinge;

blade long-lanceolate, coarsely toothed at least in distal 2/3, acuminate, ending in a short, reddish, toothed awn;

costa shortly excurrent, sparsely toothed abaxially near the tip;

marginal lamina 1-stratose, narrow, mostly erect;

lamellae 6–7 cells high, entire in side view, with nearly straight sides when viewed from above, the terminal cells in section rounded or more often transversely elliptical, ± flat-topped, with a much smaller lumen than the others and the free wall conspicuously thickened, often brownish, smooth, sometimes finely striate-papillose;

sheath cells 40–50 × 16–20 µm (3:1);

cells of marginal lamina 12–15 µm, subquadrate;

perichaetial leaves with long, sheathing bases and conspicuous golden yellow awns.

3–6 mm, loosely to densely imbricate, erect-incurved at the tips and appressed to the stem when dry, erect-spreading when moist, obtusely cucullate, often secund;

sheath broadly elliptic, hyaline-margined, gradually tapering or abruptly contracted to the blade;

blade lanceolate to ligulate, almost tubular when dry;

costa percurrent or slightly excurrent, cucullate at the apex, rarely bluntly mucronate;

marginal lamina 2–6 cells wide, entire to obscurely denticulate, slightly broader and inflexed in the distal part of blade, covering the lamellae;

lamellae 5–8(–11) cells high, minutely crenulate in profile, the marginal cells in section larger than those beneath, narrowly ovate to pyriform, smooth or very rarely indistinctly papillose;

median sheath cells elongate-rectangular, (18–)24–40 × 8–10(–18) µm;

cells of marginal lamina 11–15 µm, quadrate to short rectangular, ± equally thick-walled;

perichaetial leaves slightly longer than the foliage leaves.

2–9 cm, stout, yellowish, much longer than the leafy shoots.

1.5–3 cm, rather stout, straight or arcuate with age.

3–5 mm, pale brown, suberect to strongly inclined, 4-angled;

hypophysis cylindric but not sharply delimited;

exothecial cells not bulging or mammillose, without a central thin spot;

stomata numerous, on the distal part of the hypophysis;

peristome 300 µm, divided to 0.6, the teeth ca. 50, pale brown.

2–3 mm, short-cylindric to ovoid to globose, bluntly (4–)5–6-angled to terete, erect to horizontal to nodding;

hypophysis small, scarcely delimited, stomata large and scattered on the proximal 1/3 of the urn;

exothecium smooth, the cells variable in shape, trigonal to hexagonal, with a diffuse thin spot;

peristome pale 220–300 µm high, divided to 0.3–0.5, the teeth 50–64, slender, of uniform size, or short triangular, the alternate teeth smaller.

11–14 µm.

16–18 µm.
