some might even be edible.

Jack O'Lantern is not edible, but pretty.

This one I am not sure about.  I think it might be Suillus castanellus / Xerocomus castanellus / Boletinus squarrosoides.  See, even the Mycologist can not agree as to what it is :o)  The largest cap is about 1.5" diameter.  Very large pores that are decurrent.  What does not match the description is that the flesh is not white, it is sort of pale brown or off white.

This I make tis to be a hardy Common Mycena, growing at a base of a stump.  The largest cap is about 1".

A closer look.
