Plants forming mats, yellowish or blackish green distally, brown or blackish proximally. Stems to 7 cm; hyalodermis absent, sclerodermis present, of 1-3 layers of stereid cells, central strand present [absent]; axillary hairs to 9 cells in length, the proximal 1-2 cells thick-walled. Leaves appressed-to spreading-incurved when dry, widely spreading to squarrose, strongly reflexed when moist; triangular to ovate-triangular, adaxial surface keeled, narrowly channeled along costa, ca. 2 mm; base ovate, proximal margins long-and broadly decurrent; distal margins recurved in middle 3/4-4/5 of leaf, entire to weakly serrulate near apex; apex narrowly acute to shortly acuminate; costa percurrent, adaxial outgrowths absent, adaxial cells elongate, in 2(-4) rows; transverse section ovate to semicircular, adaxial epidermis absent, adaxial stereid band present or absent, guide cells 2-4 in 1 layer, hydroid strand absent, abaxial stereid band present, crescentic to circular in sectional shape, abaxial epidermis weakly differentiated; proximal cells weakly differentiated in a very small group medially, occasionally across insertion, rectangular, little wider than distal cells, 2-4:1, proximal cells thick-walled, somewhat porose; distal medial cells rounded rhombic to quadrate, ca. 9-11 µm wide, 1:1, 1-stratose; papillae spiculose, mostly simple to 2-fid, 1 per lumen, cell walls thickened, weakly trigonous, weakly convex to distinctly bulging on both sides. Specialized asexual reproduction not seen. [Sexual condition dioicous. Perichaetia terminal and lateral, interior leaves strongly sheathing, ovate, rounded or shortly acuminate to apiculate. Seta elongate. Capsule stegocarpous, theca elliptic, annulus of ca. 3 rows of smaller, vesiculose cells; operculum conic; peristome teeth 16, variously cleft (usually to base) or perforate, subulate, transparent, straight. Calyptra cucullate. Spores ca. 10-13 µm.] KOH laminal color reaction orange to yellowish orange.
