|discussion=<p><i>Thuidium alleniorum</i> is essentially restricted to the Atlantic and Gulf coastal plains and the Mississippi Embayment. The species is slender and loosely, sometimes irregularly 2-pinnate. <i>Thuidium alleniorum</i> could easily be taken for a depauperate expression of <i>T. delicatulum</i>. However, <i>T. alleniorum</i> is smaller and has short-pointed stem leaves with margins plane or nearly so, and the branch leaves are noticeably incurved. The laminal cells are 8–9 µm and adorned with very low papillae that are generally 2-fid so that the cells commonly appear in surface view to be 2 (or 3)-papillose.</p>
