A monotypic genus, represented by Rhexophyllum subnigrum (Mitt.) Thér. ex Hilp., is characterized by the presence of a hyalodermis, well developed central strand, oblong-lanceolate leaves that are squarrose when wet, distal leaf margins somewhat irregularly, sharply toothed, lamina 2-4-stratose in patches, and perichaetial leaves strongly differentiated. Gametophytically, Rhexophyllum can be mistaken for Leptodontium but differs by the blackish green upper portion of the plants and partially bistratose lamina. See Zander (1993: 110) under family reference.
