Plants dull green, often somewhat yellowish or brownish, irregularly branched, in dense mats. Leaves loosely appressed when dry, spreading and ± complanate when wet, asymmetric, ovate to elliptic, rounded to obtuse, 0.5–0.9 mm; laminal cells pluripapillose, rounded-hexagonal, 14–19 µm, oblate-hexagonal in several rows at margins proximally. Perichaetial leaves not enlarged, ovate, obtuse to acute, sheathing. Seta to 0.5 mm, somewhat curved. Capsule shortly exserted, oblong-cylindric, to 1 mm, stomatose; annulus and peristome absent; operculum obliquely rostrate. Calyptra 0.5 mm, smooth to ± papillose, ± plicate, plicae smooth. Spores 26–32 µm, finely papillose.

Discussion

Erpodium domingense is found in Cameron and Hidalgo counties.

Erpodium domingense might be confused with Solmsiella biseriata. Both species have pluripapillose laminal cells. The leaves of E. domingense, however, are arranged in several rows and are more or less monomorphic, whereas the leaves of S. biseriata are arranged in four rows and are distinctly dimorphic. Erpodium cubense E. G. Britton, endemic to Cuba, is similar to E. domingense but has much smaller laminal cells (9–11 µm), emergent capsules, and smaller spores (18–20 µm).
