Notes     (Last Modified On 3/9/2009)
general taxon notes:
C. Gao (1994) placed Dicranum orthophyllum in the subgenus Pseudochorisodontium, awaiting an examination of the type. He suspected that the species did not have peristome structure. After having seen its type, we conclude that D. orthophyllum is identical to D. scoparium.

Plants medium-sized to large, often robust, up to 10 cm high, dull, green to dirty green or yellowish to brownish, somewhat glossy, in dense tufts. Stems erect, simple or branched, densely tomentose below. Leaves often falcate-secund or not much altered to slightly flexuose when dry, appressed or erect-spreading when moist, lanceolate, 4–10 mm long, gradually narrowed to a slender, keeled, acuminate or acute apex, sometimes to a subtubulose acumen; margins plane, strongly serrate in the upper 1/3; costa slender, subpercurrent to shortly excurrent, serrate, ridged or lamellate in 2–4 rows at back above; upper cells rhomboidal, moderately thick-walled, smooth, more or less porose; basal cells elongate, rectangular, 85–120 µm × 8–10 µm, strongly thick-walled, porose; alar cells quadrate to rounded quadrate, slightly inflated, bi- to tristratose, yellowish brown, not extending to the costa. Dioicous. Male plants usually dwarfed, sometimes normal. Perichaetial leaves with a high convolute-sheathing base, abruptly narrowed to a short, setaceous point. Setae single, rarely double in one perichaetium, straight, 2–3 cm long, yellowish, becoming reddish with age, twisted when dry; capsules cylindric, 2–3 mm long, curved, inclined to horizontal, brownish, nearly smooth or somewhat furrowed when dry and empty; opercula long-rostrate, 2.5–3.0 mm long, sometimes longer than the urns; annuli none; peristome teeth 0.5 mm long, papillose and pale brownish above, vertically striate and reddish brown below.
