Plants: gregarious to densely caespitose, dark green to brownish when dry, mostly 1–2 cm. Leaves: monomorphic, mostly 3–5 mm, often secund to circinate at stem tips when dry; distal lamina not reflexed at shoulders, plane or channeled when wet, lanceolate to linear-lanceolate, apex broadly acute; margins absent hyaline cells, thickened and with two rows of teeth distally; medial cells distinct, 7.5–8.5 µm, bulging adaxially, plane to minutely 1-papillose abaxially; cancellinae rounded distally. Gemmae: fusiform, papillose, sparse, terminal and subterminal on adaxial apex of leaf. Seta: single, 7–12 mm. Capsule: well exserted, 1.5–2.5 mm; peristome absent or rudimentary. Phenology: Capsules mature year around.

Fertile specimens of Syrrhopodon incompletus are known in the flora area only from Florida. This is a weedy moss of low humid forests. It is the only one of its genus in the flora area that lacks hyaline cells on the leaf margins. Syrrhopodon incompletus is represented in the flora area by the var. incompletus. H. A. Crum and L. E. Anderson (1981) noted that attribution of this moss to New York is probably incorrect. According to its label, a specimen (DUKE) was collected in 1935 at Amityville, on Long Island, by M. L. Wickes. The specimen consists of three plants, two of them with sporophytes. It is very unlikely that this southern moss would occur in New York, let alone produce sporophytes there.
