Characteristics

Plants moderately robust, capitulum distinct and flat-topped; golden brown, brown or dark-brown, less commonly variegated green and brown, without metallic luster when dry. Stems pale to yellowish brown; most superficial cortical cells aporose, but a few with a single oval pore at the distal end of the cell. Stem leaves narrowly to broadly lingulate or sometimes lingulate-spatulate, (1.1-)1.2-1.4(-1.6) mm; apex broadly obtuse to obtuse-truncate and more or less fimbriate-lacerately resorbed, border in distal half narrow and often indistinct, in proximal half widened and filling up 1/3-1/2(-2/3) of the breadth at the base; hyaline cells broadly S-shaped to rhombic S-shaped, predominantly nonseptate but a few cells are 1-3-septate; efibrillose. Branches unranked, terete. Branch fascicles with 2 spreading and 1 pendent branch. Branch leaves broadly lanceolate to ovate-lanceolate, (1.1-)1.4-1.8(-2.1) mm, slightly concave, straight to slightly subsecund; apex involute; border entire; hyaline cells on convex surface with (5-)8-10(-12) semicircular to elliptical, ringed pores along the commissures, concave surface aporose or infrequently with 1-2 pores per cell in the distal portion of the cell, more numerous along leaf margins. Sexual condition unknown. Spores not seen.
