Brotherus (1925) treated four subfamilies and 16 genera in this family. P.-C. Chen et al. (1978) recognized three subfamilies and 8 genera in China. In this treatment, we include 10 genera in the Fabroniaceae.

FABRONIACEAE
碎米藓科 sui-mi xian ke
by Gao Chien and Fu Xing
 
 
Plants soft or slender, yellowish green or bright green, mostly glossy. Stems creeping, 1– 2 irregularly pinnately branched, branches erect patent; in cross section central strand absent, cortex consisting of thin-walled cells, epidermal cells slightly thick-walled; rhizoids red, growing on stems; paraphyllia rare. Leaves dense, appressed when dry, erect-spreading when moist, rarely secund, ovate or ovate-lanceolate, slightly concave, not plicate, mostly long-acuminate at apex, decurrent at base; margins plane, entire or serrate or ciliate; costa single, short and weak, rarely absent; leaf cells mostly rectangular, smooth, thin-walled; alar cells quadrate or flat quadrate. Dioicous or monoicous. Female inflorescences growing on lateral branches, paraphyses linear or not developed, regularly arranged. Inner perichaetial leaves similar to stem leaves, rarely sheathing at base, ciliate at apex. Setae slender and elongate; capsules exserted, erect, ovoid or cylindrical, apophysis short and thick, wrinkled when dry, constricted near mouth; exothecial cells lax, thin-walled, stomata on apophysis; annuli persistent, rarely deciduous; peristome deeply inserted in capsule mouth, single or double; exostome teeth in pair, lanceolate, loosely striate, without lamellae inside, rarely exostome absent; endostome segments narrowly lanceolate or absent; basal membrane low or high; opercula conic, obtuse or rostrate. Calyptrae small, cucullate, smooth, rarely remotely ciliate. Spores minute.
