Growing under redwoods. Solitary specimen. This is pretty late in the season for a Russula around here!

Thanks so much for your sound advice. I thought I still had the specimen today, but when I got home it was fairly devoured by maggots. However I was able to get spore shots in Melzer’s, though not as in focus as I would like. I need help to learn how to do this better. As to habitat, yes this was a transition area, there were several california bays and oaks nearby.
Richard redwoods are known for having countless micro-fungal
associations, but not many macromycetes. There must have been other
trees/schrubs too. I see some leaves in there that suggest more than
redwood. I suspect you must have some Oak in there.
Having said that, I am not sure what this Russula is. There are a few
mildish Russula that can have that color combination associated with
Oak, but probably not as yellow. At any rate, without the dry material
it would be silly to venture further guesses.
One or several, in focus spore shots under Melzers, clearly showing
the nature and size of the amyloid ornamentation are a must for more
serious Russula identification.
Good for testing the taste — now learn to test how far the cuticle
peels off: little 1/4, 1/3, ½, or > 1/2… from the margin to the
center. This is very useful to know in the American Russula
descriptions, as the Europeans make much less fuss about that
unusual for russulas to be with redwood. might’ve been a good one to dry!
