    Species Description - Plants red-brown. Stems branching by innovation, up to 20(-35) mm high, rounded-pentagonal in section, with rhizoids sparse. Propagula rare, rhizoidal, spherical, 30-40 µm, multicellular. Leaves nearly uniform in size, erect-spreading, twisted and occasionally incurved when dry, spreading when moist, broadly channeled, 1—3.5(—5) mm long, oblong or long-oblong, broadly acute, apiculate, the base oblong, sheathing; margins revolute along the base, distantly dentate above, with 1-2 rows of thicker-walled, less papillose, yellowish cells forming a weak border; costa percurrent to short-excurrent, dorsally smooth, the ventral cells quadrate, papillose; upper cells quadrate; basal cells differentiated across the leaf or toward the middle, about as wide as the upper cells, mostly 2-4:1, thin- or occasionally thick-walled, short-rectangular along the basal margins. Dioicous. Setae single, ca. 12-15 mm long; µm ca. 2-4 mm long, cylindric straight; annulus of 1-2 rows of vesiculose cells, deciduous in pieces; operculum to 1.2 mm long, short-conic; peristome divisions linear, ca. 100-275(-700) µm long, spiculose or ridged, lacking a basal membrane. Spores ca. 14-16 pm, weakly papillose.

    This species is similar to Morinia ehrenbergiana in appearance, but that species has bistratose upper margins.
