Entodon seductrix
Entodon hampeanus
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 hampeanus is very similar to E. macropodus, but differs in its leaves broadest at 1/3 the leaf length rather than near the insertion. Sporophytic features are needed for certainty in identification. The exostome teeth on the external surface are cross striolate near the base, more or less vertically striolate mid tooth, and papillose distally, whereas in E. macropodus they are irregularly and more coarsely striate throughout. Even the internal surfaces of the exostome teeth in E. macropodus have distinctive striations, whereas in E. hampeanus the inner surface is papillose to smooth. The species is known from two collections made in South Carolina by W. B. Schofield in the late 1950s. However, the sites are now submerged by Lake Jocassee, and the species is presumably extirpated in that location.
