Plants fairly slender to moderate-sized, pale green to yellowish, or reddish brown in sun-grown forms; forms loose to dense carpets. Stems pale green to red-brown; 3-4 layers of superficial cells. Stem leaves generally larger than branch leaves, 1.3-1.8 × 0.8-1 mm; elliptic to lingulate-spatulate, widest above middle, hyaline cells nonseptate. Branches long-cylindrical, branch leaves terete to sometimes distinctly squarrose in shade forms. Branch fascicles typically with 3 spreading (sometimes 2) and 2 pendent branches. Branch stems with single layer of cortical cells. Branch leaves 1-1.4 mm, ovate to ovate-lanceolate, gradually narrowed to an involute tip, hyaline cells somewhat bulging on concave surface and nearly plane on convex surface, with 4-8 large, elliptic, unringed pores per cell on convex surface and 1-4 irregularly rounded pores per cell on concave surface, internal commissural walls smooth to rather strongly papillose, chlorophyllous cells ovate-triangular with the widest part at or close to the convex surface. Sexual condition dioicous. Spores 21-26 µm; proximal and distal surfaces smooth, papillae indistinct; proximal laesura 0.5-0.6 spore radius.
