“intense acrid taste.” Not as hot as Lactarius alnicola, but quite hot.

As for the latex, for the ones that did bleed, I am fairly certain it did not change color. My memory of the actual color is fuzzier. There were a lot of them last year, so perhaps they’ll return this year.

I failed to record it and now I don’t recall exactly, I believe this specimen failed to produce any latex, but then I found some more close by under more birch which had milky white latex that didn’t change, but I am unsure how accurate my memory is.
