My plant id app (Seek) identifies this as beech drops. I'm not so sure after looking at google pictures.
Any which way, its the flower stalk of a parasitic plant that doesn't have chlorophyll, and steals food from tree roots.

I found this plant near the site of my 100th geocaching find. I chose a Milestone cache for the occasion. My name will now appear on the Geocache page at Geocaching.com, since I got it as a multiple of 100!
