Species: Ditrichum ambiguum

Mosses rather small, 3-12 mm high, dull-green, yellowish, or brownish, gregarious or loosely tufted. Leaves 2-3 mm long, erect-flexuose or contorted when dry, loosely erect with spreading tips when moist, narrowly lanceolate, gradually long-acuminate, narrow but blunt at the tip, serrulate at the extreme apex and often sinuate-serrulate below because of irregularly thickened margins; costa percurrent. Dioicous; perichaetial leaves long-subulate from an oblong, sheathing base. Setae 8-12 mm long, orange-yellow, becoming brownish or reddish with age; capsules cylindric, erect and symmetric or slightly curved, smooth or slightly furrowed when old; operculum high-conic, blunt; peristome teeth equally split nearly to the basal membrane into 2 terete, filiform, brown, densely spiculose divisions, obliquely directed or slightly twisted (Crum and Anderson 1981).
