Observation 91933: Agaricus californicus Peck

These were growing on the ground under some low brush on sandy soil.
Caps were up to 8.0 cm across.
Stems were mostly buried in the sandy soil and were only up to ~ 1.0 cm thick.
There was no distinctive odor and no distinctive color change when scratched. One of the specimens in the photo(front) seems to have a reddish mark on the cap but I did not see anything when I looked at them later.
KOH on the cap turned slowly light yellow.
Spores were ~ 5.3-5.5 X 4.0-4.3 microns.
The flesh was relatively thin and they were rather fragile.
Haven’t been able to pin these down. One suggestion was a possible stressed A. xanthodermus. The just don’t seem to have right look or feel for that species.

A. californicus is a good match, sporewise. Would also fit with the weak yellowing, grayish caps, and lack of a strongly crooked base.
