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.
