Didymodon norrisii Zand. is a new species of moss found in California and Oregon, U.S.A., belonging to Didymodon sect. Rufidulus (Chen) Zand. It differs most saliently from congeners by the combination of the deep brick or rose red color in KOH, costa covered by quadrate epidermal cells nearly to the leaf insertion on both sides, and apparent asexual reproduction through fragile branch apices. The new species is included in a key to the North American (north of Mexico) taxa.
