    Species Description - Plants dirty yellow-brown, about 5-10 mm high. Leaves somewhat twisted and flexuose w h e n dry, 2.5-4 mm long, broadly linear; margins entire or ± sinuolate, occasionally serrulate near the apex (or, rarely, abruptly and coarsely toothed just below it). Autoicous. Perigonia numerous, lateral (close to the perichaetium and also well below it). Setae 7-14 mm long; capsules 1.5-1.7 mm long, ovoid-pyriform (gradually tapered to a rather short neck), light-brown, becoming striate or furrowed when dry and empty; exostome teeth pale, yellowish or brownish, finely papillose, linear-lanceolate; endostome nearly as long as the teeth, hyahne, finely papillose, consisting of a low basal membrane and linear segments. Spores 16-20 µm, densely and finely papillose.

    The plants are small and yellowish or dirty-brownish, with linear (but not setaceous) leaves that are rather strongly flexuose and irregularly twisted when dry. The autoicous inflorescence, ovoid-pyriform, short-necked capsules, irregularly furrowed when dry, and endostome consisting of a low basal membrane and segments about as long as the exostome have diagnostic value.
