growing underneath pine trees. This one I am unsure about because the cap is a very light color but it has an orange tint to it, and there have been observations of white ones before.
Same Mushroom seen in http://www.inaturalist.org/observations/76783 at its end of life... Or is it? I'll be watching this log.

As the photos show, this was found under pine and coast live oak, but whether there were madrone in the immediate vicinity I failed to notice, though there is plenty of madrone in the general area. There was a somewhat unseasonable rainshower the night before. If I was more sure of my identification I would have cooked and eaten it, but I am NEVER confident enough of Amanita species to gamble my liver.
The Pluteaceae are a family of small to medium sized mushrooms which have free gill attachment and pink spores. Members of Pluteaceae can be mistaken for members of Entolomatacae but can be distinguished by their angled spores and attached gills. The three genera in the Pluteaceae the widely distributed Volvariella and Pluteus and the rare Chamaeota.
