Calymperes victoriae Dix. from the Victoria Falls, Zimbabwe, is similar but differs from this species by its oblong leaves that abruptly constrict to a short, spathulate, gemmiferous tip. The costa in section has dorsal and ventral stereid bands and incrassate surface cells. The leaves also have narrow teniolae extending from the leaf base to the thickened margin. Both species grow on wood or bark in moist environments.
Plants small, in loose tufts, dark green; corticolous. Stems 4-6 mm high, occasionally branched; in section round, central strand absent, inner cortical cells in 5-6 rows, large, slightly thickened, yellowish, outer cortical cells in 1-2 rows, smaller, incrassate, reddish. Leaves curled dry, wide-spreading wet; linear, 5.5-6.0 mm long; apex acute; base elongate, to 1.5 mm long, abruptly constricted to linear lamina; margins dentate above, with multicellular teeth, serrate at shoulders by projecting cells; in section thickened above base, forming round or quadrate knob, 4-5 cells thick, inner cells incrassate, round. Costa percurrent, gemmiferous at apex; in section wedge-shaped, guide cells 4-8, indistinct, ventral cells in 2-3 layers, incrassate, dorsal stereid band 4-5 cells thick, dorsal surface cells substereids. Upper laminal cells rounded, quadrate to transversely short-rectangular, papillose with 4-6 low, blunt papillae over lumen; marginal cells quadrate, slightly larger, smooth; basal marginal cells rectangular; cancellinae quadrate, teniolae absent. Gemmae clavate, produced on ventral costal surface at apex. Sporophyte not known in Africa.
