--><p><i>Rauiella</i> has frequently been confused with <i>Haplocladium</i> (Leskeaceae) and <i>Thuidium</i>. The genus is characterized in the flora area by leaves multipapillose on both sides, well-developed papillose paraphyllia of oblate cells on the stems (sparse on the branches), a smooth seta, and autoicous sexuality. The distal part of the costae on branch leaves is covered by laminal cells (as seen in <i>Cyrto-hypnum</i>), but in <i>Rauiella</i> the cells are also bulging on both surfaces (flat in <i>Cyrto-hypnum</i>). The paraphyllia are 2- or sometimes 3-seriate proximally and 1-seriate distally. The stem leaves of <i>Rauiella</i> are erect when dry, somewhat decurrent, and 0.5–0.6 mm in length, with pellucid costae not covered by cells apically and laminal cells bulging on both surfaces. The perichaetial leaves are enlarged and ± plicate, with rectangular to long-rectangular laminal cells.</p>
