This appears to be another example…

I may have some specimens like yours in my garage. When I can I’ll find and study them, and if anyone would like a sample I’ll send some to them. They are quite prevalent in our area.

found under the “Trametes” proposal in this obs. Looks like this type (or types) polypore needs to be better understood.
