I come across this bracket fungus quite often in my local woods growing on dead tree trunks or branches. Touching it, it feels quite hard and resilient, a bit like tough hide. I believe it’s called Hairy Curtain Crust (Stereum hirsutum), named because it has a hairy, almost velvet like appearance. It can appear in many colour forms.
