The day after I harvested the Wood Ears, we had a storm with high winds that littered the ground with debris. On some fallen branches I found these, Amber Jelly Roll (Exidia recisa) and Black Jelly Roll (Exidia glandulosa), which are easy to tell apart when seen together. Black Jelly Roll is darker, tends to grow together into clumps, and appears more brain-like. It's also not as translucent as Amber Jelly Roll. In my experience, these always grow on thin branches like these (about an inch wide). Wood Ears can be found on thicker branches.
