General Description
Plant: Loose mats or tufts. Olivaceous to brown to black, sometimes with yellowish tones. Stems 1.2-12 cm tall. Central strand of stem in X-S is weak or absent.

Leaf: When dry, leaf is erect or curved, rarely (falcate-) secound. Leaf ovate-lanceolate to ligulate, sharply keeled distally, and 1.3-3.2 mm long. Margins recurved from base to apex or to just below the apex. Margins denticulate distally. Apex acute to sub-obtuse. Costa percurrent or excurrent as an awn. Awn smooth or faintly denticulate, usually papillose on abaxial side, and sometimes decurrent.

Leaf Cells: Basal laminal cells near margin are usually quadrate. Median to upper laminal cells are usually short-rectangular, smooth, sinuose, and 8-10 ┬Ám wide.

Phenology
Capsules mature from late spring to early summer.

Diagnostic Characteristics
Protonema is persistent and its cells can reflect light, giving off a green-golden color. Look-alikes include the species of Fissidens that also occur on mineral soil. Large cell leaves easily seen with hand lens.

Range Comments
Estimated range greater than 1,000,000 square miles worldwide. Circumboreal but with highly irregular distribution. North America (northern US, Canada), UK, Scandinavia, Europe, Russia, Japan. FNA (2007) more specifically mentions for Canada: AB, BC, NB, NL, NS, ON, QC; and for the USA: AK, ID, ME, MI, MN, MT, NH, NY, OH, OR, RI, VT, WA, WI. Known in Montana from Flathead County (Elliott 2016).

Habitat
Mineral soil in crevices on the lower, sheltered areas of upturned tree root wads or on cave ceilings, crevices in soil banks, and in animal burrows. Rarely found on the shaded area of deep pits along the upper banks of a perennial stream. Occasionally found on rock. Occurs from low to high elevations (near sea level to 5,600 feet) (FNA 2007).

Reproductive Characteristics
Autoicous. Capsules are dark red or brown, and short-cylindric, 0.7-1.3 mm long.
