Didymodon nevadensis is described as a new taxon from North America, reported from southern British Columbia, southern Nevada, northern Texas, and southern Chihuahua. The new species is distinguished from its closest relative by the absence of a conical cell ending the costa, a wider costa at midleaf than below, the presence of a characteristic bulging ventral costal pad of cells, costal guide cells in two layers, and leaf margins loosely revolute. Study of extensive populations at the type locality in southern Nevada showed that this species is confined there to gypsiferous ridges and is presently represented only by female plants.
