Plants 0.5–2.2 cm. Stem leaves stiffly flexuose when dry, lanceolate to narrowly lanceolate, 2.3–3 mm; margins strongly revolute nearly to apex, entire; apex broadly acuminate to acute; basal laminal cells elongate, walls thick, nodose; distal cells 8–10 µm, 1-stratose, papillae 1 or 2 per cell, conic, small. Specialized asexual reproduction absent. Sexual condition autoicous. Seta 1–2 mm. Capsule emergent to sometimes short-exserted, narrowly to fusiform-cylindric, 1.3–2 mm, smooth; stomata superficial; peristome double; prostome absent; exostome teeth 8, separate to base, recurved, acute, coarsely papillose; endostome segments 8, well developed, usually present when capsule is old and dry, thick, stout, of 2 rows of cells, narrower than exostome teeth, yellowish brown, coarsely papillose. Calyptra conic-oblong, smooth, sparsely hairy, hairs finely papillose. Spores 13–26 µm.
Habitat: Deciduous trees, especially Populus, conifers
Elevation: moderate elevations (200-1000 m)

Discussion
The small plants of Orthotrichum elegans in rather compact tufts are quite different from the larger, loosely tufted plants of O. speciosum. Orthotrichum elegans also has fusiform-cylindric, totally smooth, and emergent to short-exserted capsules, while O. speciosum has long-cylindric, generally slightly 8-ribbed, fully exserted capsules.
