Flora of North America species comparison

smaller proximally, distal leaves 2–4 mm, deeply concave, oblong-ovate to broadly obovate distally, acute to apiculate or short-acuminate, entire or weakly serrulate distally;

costa subpercurrent to short-excurrent;

distal laminal cells thin-walled and inflated, hexagonal or oblong-hexagonal becoming much more oblong proximally.

few and scale-like proximally, distal leaves 1.5–3 mm, oblong-lanceolate to ovate or occasionally oblong-ovate, narrowed to a slender acuminate tip to about 1/6 the leaf length, entire to serrulate distally and entire proximally, costa ending at the base of or before the acumen;

distal laminal cells short-rhomboid to rhomboid-hexagonal, becoming oblong-rectangular proximally and narrowing at the basal margins.

usually (12–)20–45(–80) mm, slender and flexuose, usually hygroscopic.

5–15 mm, reddish, nearly straight.

2–3.5 mm, pyriform, asymmetric, curved to straight, horizontal to pendent or merely inclined or nearly erect, becoming sulcate when dry below the strongly oblique mouth;

annulus revoluble, operculum slightly convex;

peristome brown, papillose-striate proximally and papillose distally, strongly trabeculate, becoming appendiculate distally, forming a lattice by fusion of the tips;

endostome segments lanceolate about 2/3 as long as the teeth, yellowish, finely papillose-striate.

2–3 mm, inclined, asymmetric, pyriform with the neck as long as the spore sac, scarcely wrinkled and little contracted below the mouth when dry;

annulus none;

operculum conic-rounded;

peristome teeth linear-lanceolate, reddish brown basally, hyaline at the tips, strongly trabeculate and appendiculate, papillose-striate throughout;

endostome segments narrowly lanceolate and about 2/3 the length of the teeth, papillose.

cucullate, smooth.

cucullate, long-rostrate.

mostly 12–21 µm, finely papillose.

21–30 µm, baccate insulate.
