Dicranoweisia cirrata typically is found at middle to upper elevations in the forest growing on rotting stumps and logs. It is a small moss, smaller than the very similar Dicranum montanum. Dicranoweisia cirrata has almost no stem, whereas Dicranum montanum has more of a stem. Also, the gemmae frequently found at the base and abaxial surface of the leaves of Dicranoweisia cirrata are not found on Dicranum montanum or Dicranoweisia crispula. All have strongly crisped dry leaves that unfold when wet. D. cirrata is best differentiated from D. crispula on leaf cross-section-- D. cirrata is mostly unistratose, while D. crispula has bistratose margins and bistratose streaks in the lamina. Also, D. crispula has longitudinal cuticular ridges that appear as papillae on leaf cross section; these ridges are absent in D. cirrata.
