Exidia recisa, now known as Exidia crenata, tend to have a flattered edge with sharp ridges either side. There can also have concave depressions separated by ridges that can dry out and darken. Auricularia has a smoother edge. See some pictures here: https://wpamushroomclub.org/product/auricularia-auricula/
Note that there is one image of Exidia crenata in that set, it is correctly labelled as Exidia. I will update the web site soon.
I 100% change my mind, after looking again, particularly at the larger one at upper right! I see the “chipped” surface, like worked flint. My apologies!
This looks more like Auricularia than Exidia.

Worked flint, I like that description!
Everyone seems to know what that means, seems to be a good way to describe it!
