Amblystegium differs from Hygroamblystegium in its smaller size and weaker costa, this less than 30 µm wide at base, most often ceasing mid leaf; the costa rarely reaches 3/4 of leaf length but in such cases is straight, not curved as in Hygroamblystegium. Unlike the latter genus, Amblystegium lacks paraphyllia. Amblystegium is a terrestrial genus that sometimes occurs in swampy but never aquatic or subaquatic habitats.
