Little orange Lactarius

Lactarius substriatus is a little more reddish-brown to reddish-orange and has a translucent-striate margin.
This is the only one on MO currently labeled substriatus that I would call correct.

Although Smith didn’t mention in his description, Methven dose note the yellowing of the latex in subviscidus. Collections I have observed the yellowing is erratic. This collection showed no sigh of yellowing, even when the latex dried.

While other collections it’s really noticeable, this one yellowed after about 3 minutes.

And this one yellowed when it dried.

I also think that subviscidus and subflammeus might be the same species…

Thanks for the suggestion. I chose L. substriatus because the latex DID change to yellow. Here is what Hesler had to say about OR/WA Lactarius subviscidus…
“…. typified by burnt orange color, dry to moist or thinly viscid cap, dry stem, mild odor, white (rather than watery white) milk that does not turn yellow but may stain white paper yellow overnight, white to yellowish spore deposit, and broadly elliptic spores with amyloid warts and ridges; cited from WA, OR, (Hesler), collections from BC at Pacific Forestry Centre…”

Since I noted the change in color with the latex, can you tell me what made you choose the other option? I’m sure when you vote strongly, you have a good reason. Open ears….
