general taxon notes:
The genus is characterized by having irregularly branched stems often bearing sporophytes in lateral positions and by having a single peristome. The peristome structure often consists of only exostomial teeth or a reduced double peristomea with well-developed exostome teeth and rudimentary endostomial basal membrane. Among 90 species currently recognized in the genus worldwide, only about 15 are better understood (Crosby et al. 2000). Four species are recognized in China.

6. Mielichhoferia Nees & Hornsch.   缺齿藓属   que chi xian shu

Plants usually small, or medium-sized, in loose or dense tufts. Stems often irregularly and sprsely branched, more or less densely foliate. Leaves erect-appressed or imbricate when dry, spreading when moist; oblong-ovate to slenderly lanceolate, abruptly acute to gradually acuminate; margins entire or slightly serrulate above; costae strong, percurrent to shortly excurrent; median leaf cells linear or linear-rhomboidal, thin-walled or thick-walled; marginal cells narrowed; alar cells slightly or more often undifferentiated. Dioicous. Perichaetia lateral, often located at the bases of stems; perigonia lateral; perichaetial leaves rather large. Setae elongate, flexuose; capsules suberect to horizontal, subcylindrical or pyriform, neck well developed, with superficial stomata; annuli well developed; opercula conic, apiculate; peristome variously delicate, often single; exostome teeth linear-lanceolate; endostome (if present) hyaline, fused with very low basal membrane; cilia absent. Calyptrae small, cucullate. Spores spherical.
