Flexitrichum flexicaule looks very similar to Ditrichum gracile. Flexitrichum flexicaule has a more abrupt transition from the base of the leaf to the distal portion of the leaf. F. flexicaule also has a more convex costa on cross section. Both of these traits can be rather subtle distinctions.

Many thanks to the University of Colorado Herbarium (COLO), Erin Tripp, and Dina Clark for permitting us to photograph this specimen.
