Found these during the MSSF San Jose Camp. The caps were about 7.0 cm across and the stipe up to 12.0 cm long. Just based on appearance, the consensus seemed to be that they were a Tricholoma species. However, I later got a spore print and they were a light yellow in mass.The spores were dextrinoid (reddish brown) in Melzers. They were approx. 8.5 X 5.6 microns, elliptical, with a prominent hilar appendage(see photo). No strong odor or taste. The flesh was white and the gills were creamy to beige with little change in age. Also the gill edges were quite eroded as can be seen in the photo.
