Bryum coronatum is recognized by its short, broad, wrinkled capsule necks, leaves that are weakly elimbate, have strongly excurrent costae, and thin, lax upper leaf cells. Bryum dichotomum has a similar type of capsule and weakly limbate leaves, but that species is smaller and differs in having elongate, firm to thick‑walled upper leaf cells and quadrate, more thick‑walled basal leaf cells.

Ochi (1980) apparently chose the Richards specimen as the lectotype of this species because it is the specimen Schwaegrichen illustrated.
