Distichium inclinatum is similar to D. capillaceum and D. hagenii, differing from the former in the inclined, ovoid capsule, shorter stems, more closely set leaves, and larger spores. It differs from the latter primarily by features of the peristome: the peristome teeth of D. hagenii have a basal membrane and the teeth are arranged in eight irregular but separated groups of two teeth each, rather than being evenly spaced as in D. inclinatum and D. capillaceum.
