|discussion=<p><i>Coscinodon hartzii</i> is endemic to arctic regions of North America. Until 1992, it was known only from its type locality at Scoresby Sound in eastern Greenland. B. M. Murray (1992) reported collections from Mt. Michelson and the Philip Smith Mountains of Alaska. W. C. Steere’s (1978) and J. Muñoz’s (1998c) citations of <i>C. calyptratus</i> from those sites have turned out to be <i>C. hartzii</i>. A new location in southeastern Yukon suggests that this species may be widespread across northern North America. <i>Coscinodon hartzii</i> is recognized by its weakly 2-plicate leaves coupled with an exserted capsule and cribrose peristome. It commonly also has 3-stratose regions in the distal parts of its stem leaves.</p>
