Probably a Cellar Spider (Pholcidae)
Raccoon Mountain Caverns, Chattenooga, Hamilton County, Tennessee, USA
This creature is dead and is being eaten by fungus in Raccoon Mountain Caverns. This is a common occurrence in caves when spiders die. I thought its just interesting feel free to Frass since its dead, or do whatever.

Moved from Spiders.

a cellar spider.

It might be a harvestmen. I have seen what I am pretty sure is Pholcus in the same cave. They don't go in usually more then maybe 100 feet back into the cave. This particular cave is a "show cave" so that may explane it - they are usually around the lights in the cave.

Fungus: Torrubiella pulvinata
The fungus is Torrubiella pulvinata. The person (Mains) who originally described it mistook the victims for harvestmen, but they were in face pholcids, as discussed in:
