From the Greek gonion (referring to the sporophyte) and bryon (a moss).
Monoicous. Plants tufted, bright green to yellow-green above, brown below. Stems simple to fastigiately branched, tomentose and somewhat matted below. Rhizoids weakly papillose, especially on large stems, red-pink. Propagula absent. Leaves complanate, rarely 2- or 3-ranked, erect-spreading, twisted when dry, oblong to linear-lanceolate, widest at mid-leaf; apex acuminate; margin singly or doubly toothed; costa narrow, ending below apex; laminal cells large, lax.
Perichaetia basal in rhizoids. Calyptra elongate, thin, entire at base. Capsules cernuous, long-cylindrical, widest at mouth, often arcuate; operculum bluntly rostrate; exothecal cells rectangular to isodiametric, with uniformly thin cell walls. Peristome double; endostome c. half the length of the exostome. Spores smooth, globose.
Goniobryum is a monotypic genus found throughout the Southern Hemisphere.
