Microbryum davallianum is a minute moss of sandy habitats. M. davallianum differs from the similar M. starckeanum in the leaves of M. davallianum being relatively longer versus their width, and its spores being papillose or spicate versus merely tuberculate or smooth.

Many thanks to the University of Colorado Herbarium (COLO), Erin Tripp & Dina Clark for loaning us this specimen for photography.
