A. xanthodermus?

By appearance, A. xanthodermus is a best guess. Typically the surfaces, veil, and/or lower stipe tissue can become bright yellow when cut or rubbed, but occasionally this might fail. I wonder if it had the ‘phenolic’ odor, or something else? I’m suggesting this ID because A. xanthodermus is toxic, so pls be careful.

There is a poorly-known species described from SW Oregon, A. cervinifolius, that seems very similar to A. xanthodermus. If A. cervinifolius is really a distinct species, it would be very interesting to rediscover and fully document it.
