Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Just a possibility - could this be the remains of Biorhiza pallida - oak gall - as it seems to have rather a papery texture
Did you touch it?
I poked it with a stick and it was quite soft. Didn't need much pressure for it to sink in.
Do you recall what was inside, if it was dark spores I would say that this is likey to be Fuligo septica,but would need a sample to be sure.
