The colors & more info

The colors are accurate, I’d say.

The flesh is thin, little over 1 mm, but tubes add to the thickness; they are about 10 mm long at the base, and progressively shorter towards the margin.

The appearance is leathery, but not too tough. You can move the tubes with your finger.

It looks like this fungus absorbs water. It’s moist and appears as if it may rot rather than dry out in age, but I’m not sure about this.

Finally, there were no young fruit bodies in the whole group. It all looked old.
