Spotting

P. cinnabarinus should be the only species of Pycnoporus growing in your area. The P. cinnabarinus I've found don't have the yellow edge or the black center, so I can't offer a positive ID.

I'm not sure that Pycnoporus sanguineus occurs in North America (references say it occurs in the tropics) but it would be good to know since I have some cool red bracket fungus that I haven't been able to identify yet either.

If it is on wood it may be the pycnoporus sanguineus

but I am not sure and the dark colors among the fungi don´t make it that clear; a fungi expert may help you further...
Greetings and nice spotting.
