Observation 268346: Hymenochaetaceae Donk

A bright rusty/orange-brown resupinate growth on the inside of a large, hollow, very decayed log in mixed woods. The fertile surface appears somewhat velvety to the naked eye, but is covered with soft, bristle-like spines (setae?) visible with a 10X magnification loupe. It’s impossible to even touch the surface lightly without getting your fingers stained orange (See image # 4440). Might this be spore “dust”?

the similarity to the reference you provided (a specimen collected in 1937!). I didn’t see any mention of the substrate in this reference. The wood from which my specimens were taken was so rotted that I couldn’t take a guess on the tree species. A more experienced friend looked at this for me and immediately thought it looked like conifer wood rather than a hardwood. Seems like microscopy would be needed here.
Once again, I am duly impressed with your extraordinary memory … your ability to remember even the most obscure observations and call them to mind when you see something that looks similar. It’s a gift.
