general taxon notes:

 

The Stereophyllaceae were treated as a subfamily of the Plagiotheciaceae by Brotherus (1925). Buck and Ireland (1985) elevated it to family, with six genera: Entodontopsis Broth., Eulacophyllum W. R. Buck & Ireland, Juratzkaea Lorentz, Sciuroleskea Broth., Stenocarpidium Müll. Hal., and Stereophyllum Mitt. Juratzkaea was treated under the Fabroniaceae (T. Cao & X. Fu 2002). Only Entodontopsis of this family is recognized in China.

Stereophyllaceae
硬叶藓科   ying ye xian ke
by Li Deng-ke
 

Plants slender to rather robust, dark green or yellowish green, usually glossy, in loose or dense mats. Stems prostrate, complanate or julaceous, simple or somewhat irregularly branched; leafy branches complanate, rounded, or blunt; in cross section cortical cells thick-walled; central strand weakly differentiated; rhizoids dense, usually in leaf axils, smooth; pseudoparaphyllia filamentous or foliose. Stem and branch leaves similar, lanceolate or oblong-ovate, symmetric or asymmetric, plane or concave, obtuse or apiculate at apex; margins entire or only serrulate near the apex, not or only slightly decurrent at base; costae single, extending to 1/3–3/4 the leaf length; upper leaf cells rhombic to narrowly rhomboidal, thin- to thick-walled, smooth, sometimes prorate, or uni-papillose; alar cells often differentiated, not decurrent, consisting of quadrate or irregularly short-rectangular cells, often uneven in numbers at two angles. Autoicous, rarely dioicous. Inner perichaetial leaves small, somewhat sheathing at base, shortly to long-acuminate at apex. Setae short or elongate, straight, sometimes twisted when dry, smooth; capsules erect or slightly inclined, ovoid, curved at base, with a short neck, often constricted below the mouth when dry; exothecial cells lax, thin- or thick-walled; annuli persistent or deciduous; peristome double; exostome teeth narrowly lanceolate, bordered, with a median zigzag line, cross-striolate below, papillose above; endostome segments shorter or as long as the teeth, linear-lanceolate, keeled, perforate; basal membrane low or high; cilia 1–3 or absent. Calyptrae cucullate, smooth. Spores spherical or ellipsoidal, minutely papillose.
