Most specimens test bright- to dark-red with 2% KOH. Although this feature is not constant and is occasionally duplicated in material of other species of Didymodon, it can be helpful in naming poorly developed material. Propagula are occasional in var. vinealis and var. luridus. Like D. rigidulus this species is treated as a complex of intergrading varieties, distinctive in the extreme and in s o m e cases differing in geographic range. Some specimens cannot be assigned to any of the varieties represented in Mexico and adjacent parts of the United States.
