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.
