Discussion:

Holomitrium, Eucamptodontopsis, and Schliephackea form a generic complex of medium to large, commonly corticolous mosses marked by five morphological features: 1. a strong single costa, 2. well developed alar cells, 3. long, sheathing perichaetial leaves, 4. erect capsules, and 5. undivided peristome teeth. The genera are weakly segregrated, and features that are characteristic of one member of the group commonly occur sporadically throughout the complex. Allen (1990a) treated the complex in detail. Hegewald (1978) provided a useful revision of Holomitrium in the Antilles.

Pseudautoicous. Perichaetial leaves sheathing to convolute at base, long setaceous above, at times reaching and overtopping the capsules; capsules erect, cylindrical to oblong; stomata present; opercula subulate-rostrate; peristome teeth undivided or fenestrate, densely papillose on the outer surface; annuli absent.
