Discussion

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 sullivantii is one of the rarest species of the genus, and one of the few that most commonly grows on rock. The species is characterized by essentially terete-foliate branches (sometimes not overly obvious), reddish setae, cross striolate exostome teeth, and smooth endostome segments. The capsule is usually somewhat wrinkled when dry and empty.
