There's a second stalk behind the "flower", did that end with another flower? I'd wondered if it was parasitic or hemi-parasitic, maybe even on Solomon's Seal but I've been through my wildflower field guide and Googled with seemingly appropriate keywords but came up empty handed. I too was thinking not a fungus because it looks to have some chlorophyll in the stem, not sure it does though. Hopefully someone will recognize it.
