I got the sequence from Mike Davis, he says its a Russula and matches his 06001.

Sorry for the delayed response, I caught a cold after finding this and many things got pushed to the side. And unfortunately I have no excuse in not tasting this… I have no information from Mike on this yet, but I did ask about unknown species no. 1, he showed me pics of two different Russulas, this and what he was calling R. basifurcata which look very similar macroscopically, just one had more yellow gills (Like in your observations). They also were quite a distance from each other on the phylogenetic tree and he said he didn’t know which was the true R. basifurcata.

If not Macowanites

then well on its way to becoming one. Usually Macowanites has a small, nearly unnoticeable stipe with gills so convoluted they often become appressed to the stipe: almost Endoptychum-like.

I know that Helen Gilkey had trouble with distinguishing between Macowanites and Russula. Having spent considerable time at her favorite collecting locale (Cape Lookout) I have found many examples of Macowanites and Russula both in transitional phases.

They are not at all as easy to distinguish as may be expected.

Taste -

What was the taste here, was it mild? Not sure this is a Macowanites, there is a common enough Russula under live oak in the area, that is mild taste, and yellow spores, and is mostly off-white in color. But this one also often has gills that are all wavy and random. Here are some of my obs. on this one from the Los Trancos Open Space Preserve:


And you can see sometimes the cap is pink under some conditions.

This one was called Russula basifurcata in the Thiers’ book, and he included another form from the Sierras, but that is probably a different species. The one under the live oak, Mike Davis has been calling it unknown species no. 1, for a few years now.

Don’t you speak with Mike from time to time? You can ask him about the status of this one.

I hope Mike gets some data out for us!

I agree

Hence why I voted “could be”, I left it at Mike Davis’ lab, hopefully he can take it farther.

I gotta say…

Some of these Macowanites types just look like developmentally-weird Russula to me. Sorting out which is what is going to take a little doing, but I think there is substantial potential for non-genetic fruitbody contortions in Russula.

Darv’s recent one that looked like R. cerolens/R. amoenolens is another example…
