Perichaetia with inner leaves 1.6-1.8 mm, apex apiculate or awn short, rough, to 1/6-1/4 length expanded portion leaf. Capsule with peristome single; exostome teeth connate in pairs; endostome absent. Calyptra narrowly conic-subcucullate. Spores papillose.

Capsules mature Apr-May. Trunks and branches of saplings, living and dead trees, exposed roots, forests; low to moderate elevations (0-300 m); Ark., Ga., Miss., N.C., Okla., S.C., Tenn., Va.

Cryphaea ravenelii rare. Although similar at first glance to C. glomerata, the species can be easily distinguished by its blunt leaf apices and paired exostome teeth. Furthermore, the interior perichaetial leaves of C. glomerata have a greater tendency to be awned than those of C. ravenelii. Cryphaea ravenelii occupies the same habitats as C. glomerata, and the two species have often been collected growing together.
