Brachytheciaceae


Oxyrrhynchium hians, photographed by Des Callaghan.


Belongs within: Hypnales.

The Brachytheciaceae are a family of mosses that usually grow in mats or clumps. The family is distinguished by their pattern of pseudoparaphyllia, and the absence of papillae on the laminal cells (Ignatov & Huttunen 2002). More than 570 species are included in the family, making it one of the largest recognised families of pleurocarpous mosses. Members of the genus Brachythecium have irregular branches, more or less ovate-acuminate leaves, and inclined or horizontal capsules with a conical lid (Dixon 1924).

See also: Brachythecium salebrosum: some like it temperate.

Characters (from Smith & Smith 2004): Slender to robust plants. Stems creeping to ascending, sparsely and irregularly to closely and pinnately branched, branches straight to curved, complanate or not, spreading to erect. Paraphyllia usually absent. Leaves imbricate to spreading, rarely complanate, stem and branch leaves similar or not, plane or concave, plicate or not, broadly ovate to narrowly lanceolate, apex obtuse or rounded to longly acuminate; costa single, sometimes ending in a small projection on abaxial side of leaf, rarely forked or double; cells elongate-hexagonal to linear-vermicular, usually smooth, basal cells shorter, often porose, alar cells differentiated or not, forming auricles or not. Setae long, usually reddish, smooth or papillose with projecting cell ends; capsules erect, inclined or horizontal, ovoid to cylindrical, straight, curved or gibbous; annulus differentiated or not; lid conical, with or without rostrate to subulate beak; peristome double, exostome teeth horizontally striate below, papillose above, endostome with tall basal membrane and usually well-developed cilia; calyptrae cucullate, naked.
