|discussion=<p>Dichelyma pallescens is predominantly corticolous, distinguished by its often broadly acute to obtuse leaf apices. This medium-sized species is occasionally confused with D. falcatum. Dichelyma falcatum is usually saxicolous, has much broader leaves (0.7–1.4 versus 0.4–0.8 mm wide), exserted capsules, and perfect endostomial trellises. Dichelyma capillaceum and D. pallescens often occur in mixed collections, and both have immersed to laterally emergent capsules with imperfect endostomial trellises. Dichelyma capillaceum differs from D. pallescens in having setaceous leaf apices and long-excurrent costae.</p>
