Kingiobryum H. Rob. (Bryologist 70: 9. 1967) was originally described as a monospecific genus. The distinguishing feature of Kingiobryum (=Didymodon) is the cancellinae-like cells that are enlarged, hyaline and porose, similar to those of the Calymperaceae. See Werner et al. (2004), also Zander and Cleff (1982) with detailed discussion of distribution and ecology.

Plants forming dense tufts, green to reddish-brown, or terminal shoots green and reddish-brown below. Stems erect, to 3.5 cm tall, few branched by innovations, fragile; in cross-section hyalodermis present, outer3-4 rows of cells small, thick-walled, central strand present; thinly radiculose below. Leaves crowded, distally erect-incurved to widely incurved when dry, wide-spreading when wet, lanceolate from a sheathing obovate base, 2.8-3.8 mm long, apex bluntly acute to rounded; margins plane below, inflexed and broadly channeled above, entire; costae single, strong, subpercurrent, in cross-section stereid bands above and below guide cells; lamina distally bistratose, distal sheath and limb cells thick-walled, smooth or bulging; limb cells mostly irregularly subquadrate, 8-10 µm long/diameter, smooth or indistinctly papillose; lower and basal sheath cells differentiated, inner juxtacostal cells forming a distinct group, enlarged, rectangular, hyaline and fragile; marginal cells appearing to form a border of thick-walled narrow rectangular or fusiform cells. Dioicous ?. Perichaetia terminal; inner leaves sheathing seta, oblong-ovate, to 2 mm long. Setae elongate, to 20 mm long, twisted. Capsules erect, urn obloid, to 2 mm long, smooth when dry; annuli compound, 2-3 rows, deciduous in parts; opercula long-rostrate, 1.1-1.3 mm long; peristome apparently absent. Calyptrae not observed.
