no semi-circular conk shape, just a couple of inches thick sheet of hymenium over a good bit of the trunk.

I see what you mean about the yellow spiderwebs Noah…you’re right…it could well be from spore drop…there were virtual clouds pouring off of this guy in the sun.

Inonotus, maybe???

what about

A Ceriporia species? Excelsa turns violet in age and purpurea bruises purple but is darker brown purple.

There are Inonotus with yellow spores that look similar to this. I wonder if those are spores on the spiderweb. Was it tough or soft?

not sure what color they were exactly…

Not a good match for the photos of Leptoporus that I can find, though.

still looking for an ID on this one…
