Plants moderate-sized to robust, somewhat lax in shade forms to quite compact and stiff in open grown forms; green to pinkish green to reddish purple; forms lawns in shaded habitats and low to moderately tall, dense hummocks in open habitats. Stems green to purplish red, superficial cortical cells with spiral reinforcing fibrils clearly visible, usually 1 or 2 pores per cell, comb-fibrils lacking on interior wall. Stem leaves to 2 × 0.7 mm; rarely hemiisophyllous; hyaline cells non-ornamented, mostly nonseptate. Branches long and tapering to short and pointed, leaves loosely imbricate. Branch fascicles with 2-3 spreading and 2-3 pendent branches. Branch stems with hyaline cells non-ornamented; no or weak funnel-like projections on the interior end walls, large round pores on superficial cell walls. Branch leaves broadly ovate, to 2 × 1 mm or more wide, broadly ovate, hyaline cells non-ornamented, convex surface with round to elliptic pores along the commissures; chlorophyllous cells short-elliptic in transverse section and well-enclosed on both surfaces. Sexual condition dioicous. Capsule with numerous pseudostomata. Spores 22-30 µm; roughly papillose to nearly smooth, with distinct Y-mark sculpture on distal surface; proximal laesura 0.5-0.8 spore radius.
