Discussion

Pseudobryum cinclidioides is uncommon but one of the species easiest to recognize in Mniaceae. The broad, often green or yellow-green leaves with indistinct borders and elongate, Bryum-like laminal cells usually in diagonal rows are distinctive. The large laminal cells make it readily identifiable in the field with a hand lens.
