|discussion=<p><i>Mielichhoferia elongata</i> grows in dense, compact turfs with a whitish or sometimes bluish color that makes this species easily recognizable. The laminal cells are thin-walled, giving the plants a softer texture than <i>M. mielichhoferiana</i>. The species might be mistaken for <i>Pohlia</i>, but the turfs are usually more compact and the plants are smaller; when fertile, the gametangial buds are lateral and the sporophytes are erect or nearly so. There is substantial variation in development of the exostome teeth, but North American plants have relatively long, rather coarsely papillose segments.</p><!--
--><p><i>Mielichhoferia elongata</i> is one of the copper mosses because it often grows on mineral enriched substrates, although not always with copper. Like other copper mosses, <i>M. elongata</i> has a broad and highly disjunctive geographic range but is nowhere common. In North America, the species is most frequent in the Rocky Mountains of Colorado, where it occurs on mine tailings, especially around the towns of Ouray and Silverton in San Juan County. Two morphologically cryptic lineages can be distinguished by genetic markers within <i>M. elongata</i>, and both occur in Colorado.</p>
