Not the exact same

It was not the exact same mushroom, but it was a mushroom that was in the same patch. There were about 15-20 of these mushrooms. I still have the one in my fridge!

not xanthodryophilus…

with that yellow base. DB suggested Cortinarius elegantissimus, or something close to it. If your cap is bright yellow here, then it would seem to be a good match to that sp. concept.

Got KOH? Check out tissue staining on fresh material, too.

you may have both deciduous oak (the leaves shown) as well as live oak in that area…both occur there.

Is this really the exact same mushroom that you linked to on the BAMS list? That one showed a much more orange cap, somewhat similar to C. cedretorum, but BOTH are European species. Who knows what we have here?

suggest Valley oak.

I guess it could be C. xanthodryophilus, but the gills look rather bright, and the flesh looks very purple.
