Entodon seductrix
Entodon schleicheri
Entodon seductrix is the most common species of Entodon in eastern North America. It is recognized by strongly terete-foliate branches, broad, abruptly acute to apiculate leaves, red setae, a persistent annulus, and essentially smooth exostome teeth (the only species of Entodon with this character). The capsule is usually somewhat wrinkled when dry and empty.

Entodon schleicheri is an uncommon Western species often confused with E. cladorrhizans. However, E. schleicheri has leaves abruptly tapering with the apicalmost cell elongate, about 4:1, whereas E. cladorrhizans has gradually tapering leaves with a short (about 2:1) apical cell. In E. schleicheri the annulus is absent, the exostome teeth are striolate proximally, and the plants are usually saxicolous. In E. cladorrhizans the annulus is present, the exostome teeth are papillose proximally, and the plants are typically corticolous.
