Even though no significant gametophytic differences separate Bryohumbertia from Campylopus, the genus can be recognized by its long, slender, interruptedly foliate stems. Frahm (1982a) defined the genus by its straight setae, long operculum, annulus, and the smooth ventral surface of its peristome teeth. Bryohumbertia is similar to Atractylocarpus (here treated as Dicranodontium) in its slender setaceous leaves, ventral and dorsal stereid costal cells, straight setae, long opercula, annulus, and peristome teeth. Bryohumbertia differs from Dicranodontium, in its inclusive sense, only in its shorter upper leaf cells and interruptedly foliate habit. It is at best a weakly segregated genus, not one of the first rank.
