Description:Variety Description - Plants dark-green to brownish, tufted or gregarious; rhizoids brown to purple; stems to 2-3 cm tall but often much shorter, often freely forked. Leaves basically monomorphic, lanceolate to linear-lanceolate or nearly subulate from broad, clasping base, 4-8 mm long, variously curved-contorted to straight and appressed when dry; margins thickened, with mostly paired teeth above; leaf shoulders often with intramarginal teniola-like features; cancellinae persistent, hyaline (rarely yellowish); cells of upper lamina obscure, quadrate to elliptical, mostly ca. 5-7 x 5-12 µm, smooth or somewhat papillose dorsally, bulging ventrally; gemmae borne ventrally on costa at leaf tips. Seta yellowish-brown, 7-12 mm long; capsule 1.5-2.5 mm long; peristome lacking or rudimentary and of fragile, eroded teeth of only a few segments; operculum slenderly long-rostrate. Spores 14-19 µm, nearly smooth to finely roughened. Calyptra 2.5-3.5 mm long, smooth.

Discussion:This is a weedy moss. Its plants are dimorphic and occur in strict- and flexuous-leaved forms that may appear strikingly different from one another. However, under the microscope the leaves of the two forms are indistinguishable. The leaf bases of both sometimes bear teniola-like features at the shoulders. Variety in-completus differs from var. berteroanus in having mostly paired teeth on the upper margins and the upper margin usually lanceolate rather than commonly subulate; however, the two forms intergrade. The var. incompletus differs from S. circinatis and S. rigidus, among other ways, in its monomorphic leaves and persistent, hyaline (but sometimes yellowish) cancellinae. Syrrhopodongardneri is superficially similar but differs prominently in have sharp spreading teeth at the leaf shoulders, dark-red rhizoids, and sharply papillose leaf cells.
