Scientific Name:Hookeriopsis
Description:Genus Description - Slender to fairly robust plants in green, yellowish, or brownish mats, usually shiny. Stems creeping, irregularly branched; branches horizontal. Leaves somewhat asymmetric (the lateral leaves ± spreading and often complanate, sometimes secund or falcate-secund), ovate-lanceolate and acuminate or oblong to lingulate and short-pointed; margins unbordered, plane, usually sharply serrate above; costae 2, 1/2-2/3 the leaf length; cells oblong-hexagonal to linear, smooth or papillose because of projecting upper ends. Perichaetial leaves subulate from a broader base. Setae ± elongate, reddish, mostly smooth; capsules inclined to horizontal, oblong-cylindric with a short, thick, tapered neck, contracted below the mouth when dry, brown or red-brown, smooth; annulus none; operculum long-rostrate from a convex-conic base; exostome teeth lanceolate, red-brown, furrowed, cross-striolate, trabeculate; endostome yellow, finely papillose or nearly smooth, with a high basal membrane, keeled, lanceolate segments as long as the teeth, and no cilia. Spores small, spherical. Calyptrae fringed at base, mostly smooth.

Discussion:

Buck (1987a) split away from Hookeriopsis three genera, Brymela, Thamniopsis, and Trachyxiphium.
