This was growing in the dog run on the south side of our house in pea gravel over weed cloth. The neighborhood is in oak woodland (Quercus agrifolia).

NOTE: This is the same specimen I observed on January 5, 2016. After my initial observation I placed a large glass garden cloche over the specimen to prevent my 3 dogs from trampling on or eating it. Also, when I dug down into the gravel as far as the weed cloth I inadvertently dislodged the mushroom. After I photographed it I carefully set it back up in the pea gravel and left for a 4 day trip. When I returned the mushroom had continued it’s growth progress, and the glass cloche had created an environment that made it easy to see its white spores beneath it.

Chlorophyllum rhacodes vs. Chlorophyllum brunneum

I realize Chlorophyllum brunneum is more common on the west coast, but after reading more about the differences between Chlorophyllum rhacodes & Chlorophyllum brunneum (and examining pix) this specimen in my backyard dog run seemed to more closely match Chlorophyllum rhacodes due to its gradual (vs. abrupt) basal bulb, and movable ring.
