Autoicous ; tufts loose, more or less dense, yellow-green, fuscous at 

 base, the stems branched, i ii in. high. Leaves laxly imbricated 

 when dry, patulous or slightly recurved when moist, oblong-lanceolate, 

 more or less longly acuminate, acute, all margin revolute, nerve nearly 

 reaching apex ; cells at base elongato-rectang., with unequally incrassate 

 walls, gradually passing upward into rounded strongly incrassate cells with 

 one or more simple or bifid papillae. Caps, emersed or emergent, 

 leptodermous, faintly narrowed below the mouth, passing gradually into 

 the pedicel by a longish neck, cylindric or rarely oval-oblong when dry, 

 smooth, greenish, afterwards pale yellow, more or less furrowed ; stomata 

 superficial ; bands 8, faint or at most marked by a short row of large 

 quadrangular longitudinal cells ; teeth 8 bigeminate, rarely cleft in 

 median line, pale, densely papillose, opake, revolute, with the upper part 

 applied to capsule wall, cilia 8 white, large papillose, sinuose at margin. 

 Lid conic with red border. Cal. conic-campanulate, blackish at apex, 

 covering all caps., and with yellow hairs. Male infl. axillar, gemmiforrn,

Larger than 0. affine, with less dense leaves, the capsule longer and 

 cylindraceous, pale yellow, the bands indistinct; the branches also are 

 longer, and the seta is variable in length, but the capsule is always more 

 exserted than in 0. affine, the bands being most evident after sporing ; the 

 leaves are frequently of a reddish-brown colour with areolation varying in 

 density.
