This observation is for whatever is causing the deformed leaves on this Alliaria petiolata (prev obs).
I saw a number of Alliaria petiolata with these types of deformed leaves. They were in different places, most of which aren't likely to be sprayed with any kinds of pesticides. I looked pretty carefully, and none of them had any aphids or other apparent causative agents.

Growing on dead hardwood log in mixed woods.
Dark flexible cap surface with light margin that can be long, along the log for a few feet.
Light pore surface that can be a few times larger than cap area.
Spiky/toothy pore surface.

Seen on a field trip organized by the Natural History Society of Maryland to Hart-Miller Island. We had a great tour led by three knowledgeable guides. Thanks to NHSM and Maryland Environmental Service for making this trip possible!

My observations from the trip today, including a few from the MES property before leaving to Hart-Miller Island:
