If the staining took some time to appear and was not turning hilighter yellow quickly & consistently on at least some of the fresher specimens, I think we can rule out A. xanthodermus and A. californicus is likely.

I had a hard time seeing the yellow with my eyes. The camera could pick it up
though. It was really faint. This was the same for specimens of all ages.

Also, the yellowing was even more faint at the base of the stipe.

It seemed to take about 5-10 mins for the stain to appear. It was not consistent.

Can you clarify? Where did it stain? How quickly? How consistently? I would suggest testing several places, the cap margin, the stem base, and a cross section. A. xanthodermus can stain faintly when not fresh, or sometimes not at all. A. californicus stains faintly if at all.
Although, I have observed them a collection with strong staining at the base, but lacking in the other expected areas.

It stained a faint yellow and smelled like urinal cakes. Ewww.
