Plants small or less frequently moderate-sized, slender, capitulum flat-topped and stellate; green or dark purplish red and green, rarely green throughout, often with a distinctive bluish cast when dry. Stems red to green; superficial cortical cells aporose. Stem leaves triangular-lingulate to lingulate, 1.1-1.4 mm, apex broad-rounded to narrowly truncate, border very broad at base (more than 0.3 width); hyaline cells efibrillose, rhombic, mostly 1-septate but can be non-septate. Branches long and tapering, usually strongly 5-ranked. Branch fascicles with 2 spreading and 1-2 pendent branches. Branch leaves ovate-lanceolate, 0.9-1.4 mm, concave, straight, apex involute; hyaline cells on convex surface with very small ringed pores (less than 0.25 cell width) along commissures near apex, changing abruptly to large elliptical pores (0.4 cell width or more) basally, concave surface with large round pores in proximal margins and leaf base. Sexual condition dioicous. Spores 17-26 µm, finely papillose on both surfaces; proximal laesura less than 0.5 spore radius.
