--><p><i>Grimmia moxleyi</i> is endemic to the southwestern United States and northwestern Mexico. A thermophilous species from acidic rock, it is autoicous and usually richly provided with capsules. The species is characterized by growing in flat, easily disintegrating patches with short, keeled, muticous stem leaves that contrast with its much larger awned perichaetial leaves. J. Muñoz (2000) synonymized <i>G. moxleyi</i> with <i>G. orbicularis</i>. Although there are some similarities, <i>G. orbicularis</i> is much larger, grows in dense cushions on basic rock, has setae 2–3 mm, shiny, spherical capsules, and a mammilate operculum. Only the most proximal stem leaves of <i>G. orbicularis</i> are muticous and the basal juxtacostal cells have thick, nodulose walls.</p>
