rubbery, stipeless, gilled shelf fungus?
growing on a log.
The green half is what stuck from the log. The brown half what grew up against the log underneath.
The last photo is after I broke it for a cross-section.
I brought two specimens out of the woods and the other looked exactly like this one. The closest thing I found googling was a Crepidotus, but all the crepidotus online don't appear like the almost perfect folded circle as these did.
I'm currently doing a spore print.
