Plethodon is a genus of salamanders in the family Plethodontidae. They are also known as woodland salamanders or, more rarely, slimy salamanders. All members of the genus are endemic to North America. They have no aquatic larval stage. In some species, such as Plethodon cinereus, the red-backed salamander, eggs are laid underneath a stone or log. Young hatch in the adult form. Members of Plethodon primarily eat small invertebrates. The earliest known fossils of this genus are from the Hemphillian of Tennessee in the United States.

The Big Levels salamander is a species of salamander in the family Plethodontidae. It is endemic to Virginia in the eastern United States. First described in 2004, the specific name sherando is from Sherando Lake in the George Washington National Forest.

Weller's salamander is a species of salamander in the family Plethodontidae. This species in endemic to the southeastern mountain range of the United States. It is mainly found in North Carolina near Grandfather Mountain. These salamanders have a unique metallic spotting which distinguishes them from other Plethodon species and other salamanders in the area. They mainly inhabit cool forests with rocky areas. This species is currently threatened by population fragmentation and habitat degradation/loss.
The Yonahlossee salamander is a particularly large woodland salamander from the southern Appalachian Mountains in the United States. The species is a member of the family Plethodontidae, which is characterized by being lungless and reproductive direct development. P. yonahlossee was first described in 1917 by E.R Dunn on a collection site on Grandfather Mountain in North Carolina. The common and specific name is of Native American origin, meaning “trail of the bear”. It is derived from Yonahlossee Road northeast of Linville, where the specimen was first described.
The mud salamander, is a bright red salamander of the family Plethodontidae. It is found in streams, seeps and swamps and underneath logs, rocks and leaves. It is endemic to the eastern half of the United States with one isolated population in central Mississippi. Mud salamanders have short stocky bodies ranging from 7.5 to 16 cm long. Body color ranges with age and locality with coastal mud salamanders being more dark and drab whilst inland mud salamanders are brighter and have more contrast against the black polka dots that sporadically pattern their bodies. In the earlier years of a mud salamanders life, they tend to have crimson colored body and unspotted stomachs, as they age the salamander becomes a dark red almost purple color and acquires a spotted stomach. mud salamanders have 16 to 17 costal grooves found along the sides of the salamanders body. These salamanders are ectothermic meaning that they cannot control their body temperature and it fluctuates with the temperature. The mud salamander is readily confused with two other species, the red salamander and the spring salamander. It can be distinguished from the Red salamander by having golden pupils and a shorter snout, and can be distinguished from the spring salamander by having a shorter body length and missing the nasal ridge associated with this species. There are four subspecies in the mud salamander complex, these are the Gulf Coast mud salamander, rusty mud salamander, Midland mud salamander and the eastern mud salamander.
