Plants large to robust, gregarious, green or yellowish green above, brown or reddish brown below; terricolous or humicolous. Stems erect, 5-70 mm tall, frequently branching by subperichaetial innovations, brown or reddish brown, densely tomentose; rhizoids reddish brown, densely papillose. Leaves in successive rosettes through innovation, distant and reduced below, erect and twisted dry, widespreading wet; spathulate or oblong-spathulate, 6-11 mm long; apex acute to obtuse; margins recurved to revolute in lower 3/4 to 2/3, denticulate to dentate above; border 2-3(-4) cells wide. Costa cuspidate or short excurrent, smooth, frequently yellowish or reddish below; in section round or subround, ventrally flat or rarely concave, laminal insertion ventral, ventral cells in 2 rows, dorsal stereid band strong, stereids in 3-5 rows, dorsal surface cells incrassate, hydroids present between stereid band and guide cells. Upper laminal cells rhomboidal to short-rhomboidal, 62-85(-100) µm long, 22-30(-35) µm wide, pitted; basal cells rectangular, pitted, frequently yellowish or reddish below. Filamentous gemmae subperichaetial on stem, reddish brown, coarsely papillose. Dioicous, infrequently polysetaceous. Perichaetial, leaves triangular, apex acuminate, margins serrulate, costa aristate. Seta (27-)30-35(-48) mm long, yellowish or reddish brown; capsule inclined to pendulous, yellowish brown or reddish brown, oblong-cylindrical, straight or slightly curved, slightly contracted below mouth when dry, urn 3-5 mm long, neck wrinkled when dry, 1-2 mm long; exothecial cells irregular in shape, incrassate, smaller at mouth; peristome teeth narrowly oblong-acuminate, yellowish brown below, hyaline above, finely papillose; endostome segments keeled, tapered above, broadly perforated, cilia 3, appendiculate, basal membrane high, yellowish, finely papillose; operculum conic, mammillate; calyptra not seen; spores round, 12-18 µm, weakly papillose.
