you have Lactarius rufus in California, this might well be it, just somewhat dry specimen. It’s only the edges of the gills that have turned brownish.

The concepts are completely confused.
From Methven in Agaricales of CA:

gills pale orange
stalk surface glabrous, brownish orange.
spore print white to pale yellow

The spores are a bit small still…
But it could is “L. rufus”… sensu Methven in CA

The same reference lists the white latex of L. hepaticus (a “Rockies, East Coast and European” entity)
as changing to yellow – is that the case with this collection? It doesn’t look like the same species as Damonbrunette’s observation from NY…

Here’s Russulales News very dependable photography:

not rufus…
