Perichaetia with inner leaves 1.6-1.9 mm, awn usually distinct, denticulate, 1/5 -1/4 length expanded portion of leaf. Capsule with peristome double; exostome teeth single; endostome segments irregularly linear. Calyptra subcucullate to cucullate. Spores papillose.

Cryphaea nervosa usually grows in more humid habitats than does C. glomerata; the two species are often intermingled. The narrowly pointed leaves of C. nervosa make it easy to recognize in the field. The costa is often so prominent that the leaves of dry plants appear to be plicate.
