--><span class="statement" id="st-undefined" data-properties=""><b>Stems </b>stiff, slenderly julaceous, sterile and young material filiform, central strand distinct. <b>Leaves</b> proximally minute, 0.5–1 mm, scalelike, becoming larger and ovate-lanceolate distally; apex obtuse, subcucullate to acuminate-subulate in distal leaves; lamina 1-stratose; costa strong, less than a quarter of the leaf width, in section hydroids absent; median laminal cells (25–)30–60 × 8–15 µm, thinner, longer and narrower at the margin and forming a smooth, non-erose, indistinct border parallel to the margin. <b>Perigonium</b> a dark knob or apical rosette wider than the stem, formed by largest leaves, incurved-tubulose, to twice the length of the cauline leaves, abruptly narrowed into a tubulose acumination that can be longer than the leaf body. <b>Perichaetium</b> a large apical tuft, the leaves larger than stem leaves, to 1.5 mm, long-lanceolate and tubulose, acuminate from a broad, sheathing base, in most distal leaves rapidly or fairly rapidly narrowed into a blunt subula. <b>Seta</b> 4–10(–12) mm. <b>Capsule</b> exserted, brown, 0.6–1 mm, without stomates; peristome entire, perforate or divided nearly 1/2 distally, more or less vertically striolate to almost smooth basally, yellow and finely papillose to smooth distally; operculum to 0.4 mm.</span><!--

|discussion=<p>The only species in the genus reported for China, <i>Aongstroemia</i> orientalis Mitten of alpine regions, has been described as having an apex “sharply bent to one side at the tips” (Gao C. et al. 1999). Leaves in American populations of <i>Aongstroemia longipes</i> display this characteristic as well, although less distinctly. E. Nyholm (1986) indicated that <i>A. longipes</i> resembles <i>Pohlia filum</i> (Schimper) Mårtensson of similar habitats in Scandinavia, but that the leaf apex is sharply pointed in <i>P. filum</i>, and obtuse in <i>A. longipes</i>. For discussion of the species’ ecology see L. C. Bliss and J. E. Cantlon (1957). Aongstroemiopsis julacea (Dozy & Molkenboer) M. Fleischer, of Asia, differs in its autoicous sexuality, prominent excurrent costa, and lack of peristome (H. C. Gangulee 1969+, fasc. 2).</p>
