Used references: as described by M. Kuo on his website: Lactarius affinis…… as described by its original author (Peck, 1872) and by Hesler & Smith (1979) is yellowish brown without any hints of lilac, has a stem that lacks potholes, and has white milk that does not turn green (additionally it appears to favor hardwoods and has a slightly wider geographic range).

If I read this correctly, this variety is closely related to L. trivialis but w/o the green staining: Kuo, M. (2011, February). Lactarius affinis var. viridilactis. Retrieved from the MushroomExpert.Com Web site: http://www.mushroomexpert.com/...

mucidus sounds like a very good idea. I wouldn’t be surprised if it’s a close relative to the ones I mentioned.

Thanks, Irene

for your comment. I plan to return to the area where I collected these to see if I can find some fresh specimens. The milk did not stain and it was peppery but I’d like to see it and taste it again. L. mucidus var. mucidioides seems to fit as well except that the white milk drys pale green and stains the gills gray-green.

an awful lot of the european Lactarius trivialis – or its close relative Lactarius utilis which is brown from a young stage (but without spots..).
One important character they have is white latex that turns greyish green on drying.

Any ideas

on this would be appreciated. The latex and brittleness of the cap and stem suggest Lactarius but the gills were soft not brittle. The cap and stem were still very sticky the next morning after collecting the specimens and the hollow clavate stipe (even in the immature FB’s) seem significant along with the brown spots/pits adorning the cap surface.
