Remarks.

A worldwide temperate species found in a wide variety of habitats, but most often on damp shaded soil or fallen logs and tree stumps. Its distribution in Chile remains poorly understood but it is common in the more temperate southern regions such as Bío Bío ( Ireland et al. 2017). It is characterized by dioicous sexual condition, rosulate stems, small obovate leaves that are spirally twisted around the stem when dry, a costa excurrent into a medium to long awn, moderately well-developed limbidium, serrate distal leaf margins, and small brown rhizoidal tubers (Illustrations: Syed 1973: 270 as Bryum capillare ; Spence and Ramsay 2006: 336, as R. capillare ; Hallingbäck et al. 2008: 349, as B. capillare ; Fife 2015: 86, as R. capillare ; Lüth 2019: 923 as Ptychostomum capillare ; Holyoak 2021: 72, as P. capillare ).
