Monotropa uniflora:
The final set of images from this hike are of
this very cool, ghostly-white mycotrophic plant. Usually they are not seen in
such big groups.
I offer another photo for your interest, too.
If you visit Ponderosa State Park, make sure you stop off at the "Lily pond". It has a nice
population of Utricularia macrorhiza. See if you can get permission to wander into the
pond itself--there may be other species in there, too.
