James T's pretty mushrooms:
It looked to me to be American Caesar's Mushroom, Amanita caesarea, at first glance, because of the lack of patches on the cap.  More information is needed to confirm this ID.  False Caesar's Mushroom, Amanita parcivolvata looks very similar.

This is a mushroom we find in Connecticut and you are right that it's a Caesarea like mushroom and we joke about it every time we find it.  We call it Amanita # 19 because Rod Tulloss has been working on species descriptions for this bewildering group of closely related Amanita caesarea like mushrooms and until he publishes them he gives them numbers like # 19.   What we used to call Amanita caesarea we now call Amanita jacksonii, which is the common red American Caesars' Mushroom.  The yellow/orange form is different and there's a good picture and description of it (see remarks under comments there) on page 17 of Roger Phillips "Mushrooms of North America: I'd say until Rod or someone publishes a description of this beautiful Amanita we might as well call it Amanita jacksonii or if you prefer A. caesarea, but I warn you that the hard core name people think caesarea only grows in Europe.
