|discussion=<p>In North America, <i>Grimmia crinitoleucophaea</i> is known from only scattered localities in the American west and in three extremely disjunct sites in Canada: in southern British Columbia, near the Keele River of the Northwest Territories, and along the Dempster Highway in the Yukon. It is found on a broad range of both basic and acidic rock types. Its subgeneric placement is problematic. Gametophytically the species is inseparable from G. tergestina, of subg. Litoneuron. Indeed, based on areolation and leaf shape, L. Loeske (1913–1914, part 1) placed it as a subspecies of the latter. This close similarity may account for reports by J. Muñoz and F. Pando (2000) and D. H. Norris and J. R. Shevock (2004) of G. tergestina from North America. We have seen all cited specimens in these papers and they all represent <i>G. crinitoleucophaea</i> or <i>G. ovalis</i>. Therefore, we reject G. tergestina being in North America. Sporophytic characters of <i>G. crinitoleucophaea</i> (a short, arcuate to sigmoid seta that is eccentrically attached to the capsule, an immersed ventricose capsule with a small, mitrate calyptra, and 3–4 large stomata) clearly indicate membership in subg. <i>Grimmia</i>. Further, <i>G. crinitoleucophaea</i> and G. tergestina have never been collected together, suggesting that the two are also ecologically distinct. Despite its dioicous sexuality, <i>G. crinitoleucophaea</i> is usually fertile; its rudimentary peristome and large annulus are thus readily evident. Its 2-stratose laminal stratification separates it from specimens of <i>G. plagiopodia</i> that may have broken peristome teeth.</p>
