Fissidens hallianus, named for Elihu Hall, has been confused with F. fontanus; they can be found growing together and both have similar vaginant laminae, although in F. hallianus there can be a weak limbidiuim on the proximal margin. Moreover, the costa is longer in F. hallianus than in F. fontanus. The sporophytes of F. hallianus are terminal, the number per perichaetium usually fewer than in F. fontanus, the seta is longer, relative to the length of the capsule, and the peristome teeth are complete. Sexual reproduction appears to be dependent on seasonal exposure.
