Description
Species Description - Plants small, glossy; rhizoids purple; stems to 1 cm tall. Leaves lanceolate above scarcely broader base, mostly 2-3 mm long, involute and incurved when dry; margins of upper lamina entire, bordered all around with elongate hyaline cells; margins of lower lamina entire to ciliate at shoulders; median leaf cells isodiametric, mostly ca. 10-12 m, smooth to bulging-papillose dorsally and ventrally; gemmae infrequent, on ventral surface at leaf tips. Sporophytes nearly immersed; seta 2-2.5 mm long; capsule 1 mm long; peristome lacking; operculum 0.75 mm long. Spores 33-38 µm, finely and bluntly papillose. Calyptra mitrate-campanulate, 1.1 mm long, papillose above.

Discussion
The leaves of S. annotinus are quite variable in that cilia may be present or absent at the shoulders, and the leaf cells range from smooth to bulging-papillose. Nonetheless, this moss is easy to recognize by its low stature and soil habitat. Its mitrate-campanulate calyptra is very unusual in Syrrhopodon.

Distribution
Endemic to Amazonia; Venezuela and Brazil. Mostly on rock and soil, rarely on dead wood, at low elevations.
