Notes     (Last Modified On 3/5/2009)
general taxon notes:

 

The leaves of this species can be confused with those of Ditrichum and Seligeria, but the presence of very small plants, oblong-cylindric and striate capsules, straight rostrate opercula, very short, often papillose peristome teeth, and the presence of large, compound annuli are significant differences.

Setae 2.0–2.5 mm long, erect, yellow, twisted above when dry; capsules cylindric, 0.4–0.5 mm long, yellow to pale brown, striate when dry; opercula rostrate, 0.3–0.4 mm long; annuli well developed, compound, 2–3 rows of large cells, deciduous when mature; peristome teeth very short, lanceolate or blunt to truncate, hyaline or pale yellow, faintly to densely papillose or sometimes smooth.
