Here is what the root looked like on that (yellow and nearly dead 4 prong) from the previous pic.
It had a good multi forked root on it.
Notice the ginseng roots have a neck area with flats (previous bud scars) and a bud for next years top... then when it goes into the root area, it is fleshy and usually bulby (not woody, long and vine like - like yours).
Also on the ginseng root notice the stress rings on the body of the root. Good quality wild ginseng will have nice stress rings like that.
There is nothing like that on your roots (if those are roots) they look more like vine to me. Hope it is not pison ivy or oak.
Keep looking and good luck !
