Notes:

The present concept of the Bruchiaceae follows Buck (1979) as containing four genera - Bruchia, Pringleella, Eobruchia and Trematodon, thus the family may contain 100 or more species; in the Neotropics four genera and about 17 species. Placed in the Dicranaceae by past and some present authors. Snider (in Sharp et al., 1994; see general references) suggests that Eobruchia exhibits peristomal features similar to the Ptychomitrium. The conspicuous, elongate neck with numerous stomata is a distinctive feature of the family.

 

Esta familia, localizada en Dicranales, contiene cinco géneros con menos de 100 especies; en el Neotrópico cuatro géneros y ca. 17 especies. En Bolivia son aceptados un solo género y dos especies. El cuello conspicuo, alargado y con numerosos estomas es una característica distintiva de la familia.

Plants very small to somewhat medium sized, solitary or forming short tufts. Stems short, simple or few branched by innovations. Leaves mostly progressively larger distally, lanceolate to narrowly lanceolate or subulate from an oblong or oblong-ovate base; margins plane or recurved, entire or distal tips serrulate; costa single, subpercurrent to short excurrent; laminal cells smooth. Gemmae absent. Autoicous. Sporophytes terminal; perichaetial leaves often larger and longer than stem leaves. Setae short to elongate, erect or curved to flexuose, smooth. Capsules immersed to exserted, urn obloid to pyriform with a neck distinctly elongate, occasionally as long or much longer than the urn; stomata numerous in neck region, superficial; annulus often well developed; opercula absent or present and rostrate; peristome absent or present with 16 teeth. Calyptrae cucullate or mitrate. Spores variously ornamented.
