too bright in its orange colors

usually the caps are much duller looking, a dirty brownish olive orange.

but that size is a clincher. I didn’t see your original measurement in the description.

my Alaskan collections were also quite small. without that size tho, it was not obviously aurantiosordidus.

thanks for presenting your arguments. actual details always beat so and so said so.

and now, we have confirmed a bit more cap color range here on MO to help develop a better species concept.

hopefully others will follow.

so it’s all good.

Still don’t understand “too bright”…

If you mean the green colors, the descriptions in both MotRC and the original description in Mycotaxon 96 pp302-304, note the cap “colour pale dirty orange when young, zonations slightly paler, soon flushed or mottled with olive to greyish green, often darker green centrally but green tinges mostly lacking at the margins”.
Also, there is the emphasis on the small size of this species…“Pileus 2-5.5 cm diam.” All of these were less than 2.8 cm in diam.
I tend to trust Noah in these type of ids because of the amount of time he has spent in this corner of NW Calif. and the significant amount of time he has spent on looking at Calif. Lactarius.

your caps look too bright for aurantiosordidus.

and we can’t see the context/latex color. Were these IDed by Noah in hand or by photo?

why not piceus?

not every lactarius bleeds well, as you know.

pity that Noah and Christian couldn’t share their many images of this species here, instead of just photo free lists. The more examples we see the better all of our species concepts! And of course, Noah couldn’t possible make an ID error, right?

Noah’s photo in Redwood Mush looks like both of my photos of this species on MO. The color is strikingly different than what you show here.

So no, I am not buying the ID, no matter who made it.

I don’t understand the comments.

They look very much like the photo/description of Lactarius aurantiosordis in Mushrooms of the Redwood Coast, including habitat, and id’d by Noah. In fact. they are even slightly less bright. Spore size could be considered a problem however. Need to read original description.
