    Species Description - Plants of medium to large size, in yellow-, olive-, or dark green to brownish mats, or among other bryophytes; stems highly variable, to 10 cm long, with leaves, to 4-5 mm wide, often much smaller, often becoming erect, small-leaved and gemmiparous at the tips, irregularly branched; branches scarce to abundant, leafy or flagelliform, or short sexual, ventral-intercalary from the axils of the underleaves; stem in transverse section with the cortical cells similar to those of the medulla. Rhizoids frequent, long, in hyaline, yellowish or brownish tufts from the bases of the underleaves. Line of leaf insertion oblique and curved in the upper part. Leaves distant to imbricate, ascendant-spreading, ovate from a broad base, the dorsal base curved, the ventral base straight or sometimes decurrent in less robust plants, narrowed to the shortly bifid apex, the segments short, triangular from a 2- to 4-celled base, ending in a 1- or 2-celled tip, the sinus U-shaped; cells of the upper part of the leaf hexagonal, regular, 26-39 X 26-39 µ, the walls uniformly thin, without trigones, the cuticle verruculose. Underleaves conspicuous, distant, broader than the stem, transversely elliptical in outline, deeply set on the stem, bifid and with a broad sinus, the teeth of segments usually broad, blunt, the lateral margins convex and with a second broad tooth or projection on the margin, additional short acute teeth sometimes present. Plants monoicous or dioicous (usually sterile). Male inflorescence catkin-like, the bracts and bracteoles scale-like, in up to 6 series, concave, imbricate. Female bracts and bracteoles in 3 or 4 series, small, scale-like, remaining at the mouth of the sac. Perigynium cylindrical, to 2 mm long, bearing rhizoids. Sporophyte not seen.

    Distribution and Ecology - Habitat: In dense or lax mats on moist banks, shaded rocks, trees or decaying logs, or scattered among other bryophytes.
