Campylopus angustiretis differs from all other species of the genus by its elongate distal laminal cells. Thus it is not certain if it actually belongs to this genus. Because of the lack of sporophytes a decision cannot be made. It has been treated as a variety of the sympatric C. surinamensis and superficially resembles certain expressions of that species (described as C. donnellii). It differs, however, by a narrower costa, the awn not coarsely serrate, the transverse section of the costa showing larger hyalocysts, and distinctly keeled leaves.
