Okay, my curiosity peaked and I went out to the spot near my house where it was growing. I have the sucker beside me. Yes it is a Lactarius, good call Shane. Latex is white and after 15 mins is still white. Old wounds are yellowish rust colored. Taste is mild for a Lactarius. I am not running to spit it out. KOH stains the cap pale yellow, removes the lilac color. Looks like it keys out to L. argillaceifolius var. megacarpus

It could be a Lactarius

the cap is zoned and the gill attachment is wrong for clitocybe. I’ll check tomorrow.

Christian, I don’t think this is a Lactarius. I didn’t look for latex. I thought it was one of the blewits ( very pale ones) I saw here last year. I’ll go back tomorrow and check it out properly. Always worth a second look!

Did you happen to see the color of the latex?
