|discussion=<p><i>Sarmentypnum trichophyllum</i> is occasionally reminiscent of <i>S. exannulatum</i>, but the distinctly pencil-like branch and shoot apices, excurrent costa and long, brown axillary hairs when young (shorter and normally hyaline in <i>S. exannulatum</i>) separate it. For the differences between <i>S. trichophyllum</i> and <i>Drepanocladus longifolius</i>, see discussion of the latter. <i>Sarmentypnum trichophyllum</i> has been reported from many areas of Canada (R. R. Ireland et al. 1987); however, it seems to be widespread only in western Alaska, and few specimens from outside this area have proved to belong to this species. The species was reported from two localities in Greenland by G. S. Mogensen (1995), but those specimens are <i>S. exannulatum</i>. In northern Europe, <i>S. trichophyllum</i> has been found at higher altitudes (750 m), and there is no reason to assume that the species is restricted to lower elevations in North America.</p>
