|discussion=<p><i>Grimmia torquata</i> is a montane-alpine species with a preference for shaded habitats. It grows in hemispherical cushions on steep, damp rock walls. Preferred substrates are granite, gneiss, quartzite, and schist. Its distribution reaches from near sea level in the Arctic to above 4000 m on Mexican and Hawaiian volcanoes. The species is easily recognized by its yellow-brown cushions of plants, which have contorted leaves when dry, and their brown gemmae, which are borne at the bases of older leaves. In densely shaded habitats, the cushions are light green; on exposed rock, they are usually brown. Although the species has a wide distribution, it is seldom present in quantity, usually growing in a small number of cushions in one habitat. Sporophytes are very rare worldwide and have not been found in eastern North America (H. A. Crum and L. E. Anderson 1981).</p>
