(H. A. Crum & L. E. Anderson) Ochyra

Fragm. Florist. Geobot. 37: 212. 1992,.

Basionym: Tortula ammonsiana H. A. Crum & L. E. Anderson Bryologist 82: 469. figs. 3–5. 1979
Treatment appears in FNA Volume 27. Treatment on page 623. Mentioned on page 618, 621.

Stems 5–10 mm. Leaves infolded and twisted when dry, recurved when moist, broadly spatulate, 1.5–2.5 × 0.6–0.8 mm; margins plane, entire before but with a few teeth near the apex; apices acute; costa percurrent, yellow or brown, smooth; basal-cells abruptly differentiated, narrower toward the margins; distal cells quadrate to hexagonal, 10–15 µm, bulging, with about 4 papillae per cell. Specialized asexual reproduction propagula borne on stalks in axils of distal leaves, leaflike, 0.25–0.45 mm, green, papillose, costate. Sexual condition dioicous (perigonia and sporophytes unknown).

Elevation: moderate elevations
