|discussion=<p>The propagula of <i>Aulacomnium androgynum</i>, borne in spheric clusters at the ends of naked branches, are a distinguishing feature. This is the only species of <i>Aulacomnium</i> with small lanceolate leaves that are serrulate mainly beyond mid leaf and shortly rounded at the insertion. The species also lacks a hyalodermis. The distal laminal cells of <i>A. androgynum</i> are round or ± oblong, 1-papillose on abaxial and adaxial walls, with blunt, long papillae and thick walls. The basal laminal cells of the inner perigonial leaves are elongate to rhomboidal, large, and smooth.</p>
