Recognized by sight: Just a hunch from the orange spores and incurved cap margin. Also has that pinkish upper stalk indicative of some gym’s. See if veil stays persistant. Also dryish shaggy cap seems to be indicative of a gym, as well. I am however, no expert.

not typical lilaceps…

but doesn’t fit neatly into any of the other species in Steven’s Agaricus Key to CA either.

Habitat? Tree associates? KOH reaction?

Prob. best to leave it at Agaricus sp. for now.

Other options

Include A. benesi which should be paler and with upright scaliness on the cap.
A. fuscofibrillosus which should redden strongly over about 20 seconds and have two or three brown bands around the lower stipe, and the cap doesn’t start out white.

How quickly/strongly did these stain reddish/pinkish? Can you give us a spore size?

I pick A. lilaceps regularly and these are a smaller mushroom with a thinner cap and stem. A. lilaceps is very chunky.

I don’t think

Agaricus lilaceps deserves an “As If” given the information included with the observation.
I was considering one other species, but I think Darv is probably correct. Look at the ochre stains on the broken stem at left, the yellowing of the veil, the rather robust stature and pale to brown cap, and growth with cypress.

Alan – what do you think this Agaricus is, and why?

Why not A. lilaceps?

I don’t think I am seeing what you are.
