Two species, Dicranum dispersum and Sciuro-hypnum ornellanum, are reported for the first time from North America. Both species were discovered among collections made in northern Alaska in the Philip Smith Mountains and the Arctic National Wildlife Refuge in 2004, and S. ornellanum also was collected in 1993 on the Seward Peninsula. Brief descriptions and illustrations of both species are provided.
