Stems pale green to brown, branch bases sometimes reddish; superficial cortex of 2-3 layers of moderately thin-walled and differentiated cells. Stem leaves 0.8-1.1 mm, triangular-lingulate to lingulate, concave, spreading, apex broadly obtuse, hyaline cells fibrillose in apical region. Branches slender and tapering, often 5-ranked and decurved, leaves somewhat elongated at distal end. Branch fascicles with 2 spreading and mostly 1 pendent branch. Branch stem green, cortex enlarged with conspicuous retort cells. Branch leaves ovate-lanceolate, 1-1.7 mm, straight, slightly undulate and spreading; margin entire, hyaline cells on convex surface with 1-5 pores in cell ends and free near apex, on concave surface with round wall thinnings in cell ends and angles; chlorophyllous cells triangular in transverse section and well-enclosed on concave surface. Sexual condition dioicous. Spores 25-33 µm; smooth to finely papillose on both surfaces; proximal laesura approximately 0.5 spore radius.
