Recognized by sight: At least that is the common name in Cali. I believe the yellow in the gills was washed out a bit here with the camera flash.

of “joachimii” can be seen here:
The photo is from Oregon.
But I’m not convinced that it’s the same as the european one – I choose not to beleive it until I have seen DNA evidence..

Thanks Irene!

I had googled Tricholoma joachimii and could not find any USA information.

and so are luteus & aureus. The oldest name is equestre, introduced by Linnaeus,
but Elias Fries chose to use Persoons name flavovirens (from Netherlands), and mentioned the three others as synonyms.
I don’t know how the nomenclatural rules make one or the other name the right one to use, just that they apply to the same species.
What we still don’t know much about, is how many species there are in this group around the world.

Has anyone here seen T. joachimii? Maybe this isn’t it, if the photo shows wrong colours, but it (or a similar species) is known from coastal areas in the PNW, also growing with pine.

equestre is the European name for a similar fungus.

Yes, the gill color shows much more yellow. Why is T. flavovirens used and not T.equestre?
