Plants moderate-sized to robust, open, very stiff and slender, less frequently compact, capitulum large, flat, and stellate; typically deep green in shaded sites to yellowish brown in more open sites; without metallic lustre when dry. Stems pale green to yellow-brown; superficial cortical cells with a single large round pore in distal portion of cell usually free from cell wall. Stem leaves lingulate, broadly lingulate to lingulate-spatulate; 0.8-1.3 mm, apex broad, truncate and lacerate, border broad at base (more than 0.25 of base); hyaline cells rhomboid, efibrillose, and rarely septate. Branches typically long and tapering, not 5-ranked. Branch fascicles with 2 spreading and 1-2 pendent branches. Branch stem with solitary retort cells or in groups of 2-3, necks moderately distinct. Branch leaves ovate to ovate-lanceolate, 1-1.4(-1.8) mm, concave, straight, apex strongly involute, margins entire; hyaline cells on convex surface with numerous elliptic pores along the commissures, grading from small pores near the apex to large pores near the base, concave surface with large round pores along the margins and base. Sexual condition dioicous. Spores 21-27 µm, moderately to coarsely papillose on both surfaces; proximal laesura less than 0.5 spore radius.
