    Species Description - Plants in dark-green or yellow to brown mats. Secondary stems loosely spreading; branches usually decurved when dry, tapered or flagelliform-attenuate. Leaves curved and homamallous, loosely erect when dry, erect-spreading and often +- complanate when moist, broadly oblong-lanceolate from an ovate, broadly decurrent base, acute (sometimes blunt or nearly rounded) and usually ending in a pale apiculus; margins plane, papillose-crenulate all around, often sparsely serrulate near the apiculus; costa ending well below the apex; cells irregularly hexagonal, densely papillose. Perichaetial leaves pale, sheathing at the base, with wide-speading, sharply pointed acumina; costa slender to obsolete or lacking; cells elongate and smooth. Setae 13-27 mm long; capsules 2-3 mm long, cylindic, smooth, light-brown; annulus none; aperculum obliquely rostrate; exostome teeth pale-yellow, becoming white, often faintly cross-striolate below, bordered; endostome segments long, linear, often narrowly perforate along the keel, cilia rudimentary or none. Spores very finely papillose, 10-15 µm. Calyptrae smooth.
