light-green or yellowish green in loose tufts 5–25 mm high; stems nearly naked
below, sclerodermis and central strand present; rhizoids reddish brown, smooth,
clustered at base of stems. Upper leaves 2–3 mm, lower leaves reduced, leaves
crowded at apex, erect-contorted when dry, erect, concave when wet, soft and
flaccid, deeply concave, obovate‑oblong, acute to short-acuminate, not or
weakly decurrent at base; not bordered, margins plane to erect, often undulate
when dry, entire to somewhat serrulate above; costa subpercurrent to shortly
excurrent; upper cells hexagonal to rhomboidal-hexagonal, with thin, bulging
walls, 37–62 x 12–30 μm, basal cells enlarged, rhomboidal-hexagonal,
90–112 x 70–87 μm, alar cells not differentiated. Autoicous. Paraphyses
clavate with enlarged, subglobose to ellipsoid cells. Setae 15–70 mm long,
brownish red, cygneous when wet, not or weakly twisted when dry. Capsules 3–4
mm long, pyriform, suberect but very oblique at mouth, gradually tapered from
the neck, plicate when wet or dry; opercula 0.2–0.5 mm high, weakly conic, not
or minutely apiculate; annuli compound and revoluble; peristome diplolepidous,
exostome teeth from a short, yellow, densely papillose membrane, brownish
yellow below with well-developed, dark-red trabeculae, hyaline at tips, densely
striate-papillose, asymmetrically curved above and united at tips with a
latticed central disk, endostome lacking basal membrane and cilia, segments
opposite and united at base of exostome teeth, broad below, abruptly narrowed
above, pale-yellow, densely papillose, 2/3 the length of the exostome. Spores
