Leaves often deciduous, loosely erect and flexuose to ± falcate-secund, 2.5-8 mm long, subtubulose from near the base, strongly auriculate and narrowly lanceolate, gradually narrowed to a long, ± rough, setaceous point; margins closely serrulate in the upper 1/3-1/2 (occasionally subentire), entire below; costa 1/3-1/2 the width of the leaf base, (70-)150-210 µm wide below, long-excurrent; alar cells inflated in well-marked, hyaline or reddish auricles; lower basal cells short-rectangular, ± enlarged and extending upward for some distance near the costa, rather pale, usually firm-walled, sometimes ± pitted, narrower toward the margins; upper basal cells firm, rectangular, becoming linear toward the shoulders; cells of upper lamina rectangular to linear, generally elongate. Setae about 1 cm long, erect-sinuose when dry, ± curved or cygneous when moist; urn of capsule ca. 1.5 mm long; operculum about as long as the urn. Spores ca. 11-12 µm.
