Plants 1–2 cm, in loose tufts, yellow-green. Stems unbranched.

Discussion

Tayloria froelichiana can be distinguished most readily from T. hornschuchii by several sporophytic traits: hypophysis twisted and conic, tapering quickly to the seta; operculum deciduous, with an included columella; exostome reticulate to striate, teeth paired, eight in number; and sexual condition cladautoicous or synoicous. The leaves of T. froelichiana are slightly keeled; the proximal leaves are somewhat radiculose. In addition, T. froelichiana differs from T. hornschuchii by the lack of axillary propagula and longer basal (125–195 µm) and apical (75–115 µm) laminal cells.
