    Species Description - Plants red-brown to yellow-brown above, red-brown below. Stems branching by innovation, 5-25(-30) mm high. Propagula often present o n rhizoids, red to red-brown, mostly 45-115 µm long, obovoid, often with cells irregularly bulging. Leaves becoming larger above, erect-incurved or slightly spreading and ± twisted when dry, spreading to 45-60° above an erect base when moist, nearly flat or broadly concave, about 1-1.8 mm long, ovate-triangular to short-lanceolate, sometimes apiculate by 1-3 weakly papillose, pellucid cells, with a distinctly oblong-sheathing base, decurrent at the costa; margins recurved in the lower half, entire (or occasionally ± serrulate at the apiculus); costa percurrent; upper cells quadrate, 10-13 µm wide; basal cells differentiated toward the costa or across the leaf, up to 12 µm wide and 2:1, mostly rectangular, hyahne or yellowish, weakly papillose. Dioicous. Setae 7-8 mm; capsules 2.2-2.5 mm long, ellipsoidal; annulus of 1-2 rows of vesiculose cells, revoluble and fragmenting; operculum 0.5-0.9 mm long, short- to long-conic, with cells in straight rows; peristome none or rudimentary, the teeth only 25 µm long, erect, subulate, pale-yellow, spiculose, without a basal membrane. Spores 12-15 µm, weakly papillose.
