Plants in dense, 1-3 cm, dark green mats, usually reddish tomentose below. Leaves 5-7 mm, erect-patent when wet, flexuose when dry, the distal leaves sometimes curved and secund, lanceolate, ending in a straight concolorous tip, which is serrate in the distal part; alar cells hyaline or reddish; basal laminal cells thick-walled, rectangular, ca. 4-5:1, narrower toward the margins; distal laminal cells quadrate to oblique or short rhombic; costa filling 1/2-2/3 of leaf width, in transverse section showing abaxial groups of stereids and adaxial small substereidal hyalocysts which are smaller than the median deuters. Specialized asexual reproduction by microphyllous branches in the axils of the distal leaves. Sporophytes not known in North America.
