Trametes versicolor
Fungi with blue, grey, and yellow coloration.
Fallen, dead tree.
Thanks for the IDing tips - these fungi were found on a fallen pine tree (you can just barely see some of the bark in the upper right corner). I've gotten better about taking pics of the undersides as well. I'll change the ID to Turkey Tail.
Turkey tails are common, as are Stereum ostrea, or false turkey tails. Since we do not have pics of the bottoms to see the pores, it is almost impossible to tell. However, S. ostrea tends to grow in a funneled or bent shape, so I am inclined to say they are T. veriscolor.
Turkey Tail fungus (as that what it resembles) comes in a variety of colors. I have a lot in the woods here in Pennsylvania also.
If you can id the tree species it is growing on, or at least indicaet hard wood or soft wood, it can help id mushroom species.
