Growing near/on exposed shale in thin soil. Unfortunately, I did not have a loupe to examine stem hairs, but they are clearly spreading. Aerial parts of the stem are glabrous and glaucous. The basal leaf hairs are obviously bifurcate in photos, and with ciliate margins. Cauline leaves glabrous and clasping. Keying from Borodinia/Arabis led to Arabis pycnocarpa, but Turritis glabra looks better and perhaps was missed by bypassing an earlier key.

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.

ORANGE photos were night before and GREEN were the next morning, less than 12 hours later.
Indented, cup shaped, many in a group. Bright orange night before then changing to green cap with red stipe.
Growing on cut log. Log possibly box elder.
