--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>small to medium-sized, in moderately loose to dense tufts, green or yellowish to brownish. <b>Stems</b> creeping to ascending, not attenuate, unevenly foliate, julaceous or not, irregularly to regularly pinnate, branches moderately densely terete- to complanate-foliate, sometimes julaceous; central strand present; pseudoparaphyllia acute; axillary hairs of 3 or 4 cells. <b>Stem</b> leaves erect, patent, or rigidly spreading, imbricate-appressed, ovate, ovate-triangular, or lanceolate, moderately to strongly concave, not or slightly plicate; base decurrent; margins serrulate proximally, serrate distally; apex gradually tapered, acute, acuminate, truncate, apiculate, or cucullate; costa to 40–80% leaf length, broad throughout, terminal abaxial spine present or absent; alar cells subquadrate to short-rectangular, large; laminal cells elongate-flexuose, walls moderately to strongly thick, prorate; basal cells shorter, wider. <b>Branch</b> leaves smaller, narrower; apex acute to acuminate (sharper than stem leaves); costal abaxial surface more strongly serrate; laminal cells more strongly prorate. <b>Sexual</b> condition dioicous; perichaetial leaf acumen reflexed. <b>Seta</b> brownish orange to red-brown, rough. <b>Capsule</b> inclined to horizontal, brownish orange to red-brown, cylindric, not or slightly curved; annulus separating by fragments; operculum long-conic, broadly rostrate; peristome xerocastique, perfect. <b>Calyptra</b> naked. <b>Spores</b> 13–18 µm.</span><!--

--><p>The circumscription of <i>Bryhnia</i> needs a re-evaluation with DNA markers since morphology seems to be misleading. In Japan and adjacent areas, N. Takaki (1956) accepted 15 species within <i>Bryhnia</i>, but only six survived the revision by A. Noguchi and Z. Iwatsuki (1987+); most were synonymized with <i>B. novae-angliae</i>. Among North American species, <i>B. graminicolor</i> is not closely related to the core group and possibly should be segregated in its own genus.</p>
