are of the same individual mushroom. For the last photo (from which the thumbnail derived) I tweaked the camera settings in an attempt to better reproduce the colors I saw in the field.
In the other three photos, everything looks the same yellow color. In the field though the folds looked a more apricot color than the rest of the fruit-body, and I tried to get the camera to take a picture that would better reflect that color. Unfortunately it didn’t work perfectly; the folds are maybe a bit too pink and the rest a bit too orange, though at least they’re not identical colors in that picture.
