Seta pale-yellow, 4–5 mm, straight, not hygroscopic. Capsule yellow, elongate-cylindrical from a neck half or more the total length, 2.5–3 mm, weakly sulcate when dry and empty; exothecial cells scarcely thickened, narrowly oblong (3–4:1) near the mouth and transversely elongate in 4–6 rows proximal to the mouth; operculum conic-rounded; peristome pale brownish yellow, lanceolate with thin trabeculae proximally and terminating in a 1–2-celled hyaline evanescent tip, striate basally and nearly smooth at the tips, endostome not seen.
