When: 2007-01-07
Collection location: Los Trancos Preserve, Palo Alto, Santa Clara Co., California, USA [Click for map]
No specimen available
Notes:
These were pretty big, the large one is about 8 in across in the cap. The brownish stains of the gills from the latex can be seen in the second photo. When I found these they were completely hidden from view under the leaf duff. Pretty big samples to be so hidden.
Also in the first photo there is a newt in the hole, which is probably too hard to see in this photo. I have a better photo of the newt, but this is mushroom observer, not newt observer…
