|discussion=<p>Variety icmadophilus is similar to <i></i>var.<i> gracilis</i> in general aspect but the leaf apices are usually hairlike and protuberant, the distal laminal cells are usually smooth and their lumens usually angular. It is common on the North American Plains, where it may occur in association with <i>Didymodon fallax</i>. The former plant is green in young parts, sometimes with a blue-black cast, but commonly red basally, and has boat-shaped elongate, erect leaves that are only slightly incurved when dry, laminal cells smooth and costa excurrent and often flexuose. <i>Didymodon fallax</i> has light green to reddish green color throughout and triangular leaves that are often incurved or even catenulate when dry, costa percurrent and leaves papillose. Variety icmadophilus is rare in the East: Tennessee, Sharp 34606, TENN, and New York, Drummond 120, NY, are apparently this variety.</p>
