--><p><i>Scopelophila</i> is a small genus (R. H. Zander 1993) of “copper mosses” (see reviews by A. J. Shaw and L. E. Anderson 1988; Shaw 1993) associated with mineralized soils. <i>Crumia</i> is similar but is quickly distinguished by its stem central strand, intramarginal laminal border, and distal laminal cells usually distinctly papillose.</p>
