==Description== ''Plethodon elongatus'' is a medium-sized, slender salamander. Adults are {{convert|6|-|7.5|cm|abbr=on}} from snout to vent, and {{convert|11|-|15|cm|abbr=on}} in total length. Limbs are relatively short; toes are short and slightly webbed. Dorsal coloration is dark brown or black. A reddish or reddish-brown straight-edged mid-dorsal stripe may extend from the head to the tip of the tail; the stripe may be less pronounced in older animals.<ref name=AmphibiaWeb/>
==Life history== ''P. elongatus'' is a fully terrestrial salamander. Clutch size is three to 11 eggs (mean eight). No free-living larval stage exists, and juveniles hatch completely metamorphosed, measuring about {{convert|18|mm|abbr=on}} in snout–vent length.<ref name=AmphibiaWeb/>
==Habitat and conservation== The species occurs in areas of moist talus and rocky substrates in redwood or Douglas fir forests. It is typically encountered among moss-covered rocks or under bark and other forest litter, usually avoiding very wet areas.<ref name="iucn" />
The Del Norte salamander is locally abundant in suitable habitat. It is threatened by habitat loss caused by logging.<ref name="iucn" />
