Description:Genus Description - Plants slender to moderately robust, dull, olive-green, yellowish, brownish, or blackish, creeping or ± pendent, irregularly subpinnate. Stem and branch leaves similar, erect or imbricate when dry, spirally arranged, somewhat concave, usually plicate, ovate or lanceolate from an auriculate base, acute to gradually long-acuminate or hair-pointed; margins papillose-denticulate throughout; costa single, ending above the midleaf; cells short-rhomboidal to linear, thick-walled, papillose, shorter and broader at the base and rhombic in many rows at the basal angles. Dioicous. Perichaetial leaves lanceolate, long-acuminate. Setae short, rough; capsules immersed or exserted, oblong-ovoid; exostome and endostome papillose. Calyptrae cucullate or mitrate, usually hairy.

Discussion:

The leaves are only moderately concave, ovate-lanceolate, auriculate, and generally plicate, with a single costa and variously elongate, pluripapillose cells.
