Staining

I think this is pretty much what I see for the Pine Barrens Leccinum (strong vinaceous-pink, then violet then finally almost black, but the staining action is very quick; the tubes stain pink, too). Some specimens have turquoise or aquamarine stains on the lower stipe/base.
I am having difficulty with interpreting the color of the initial staining, so I don’t know if yours and mine belong to stirps Aurantiacum or stirps Insigne in the sense of Smith & Thiers.
I found some today and will be posting later.
M. Kuo will be visiting our club in October. As you know he is working on the NA Leccinum phylogeny. I am sure he would be interested in your samples.

insides stained slowly. It some pink that turned reddish or violaceous then then blackish. I put 12 of them in the dehydrator tonight. Cut in half. My wife wanted to eat them but I told her we need to save them because I want to work on them. It was strange nothing blued when cut etc but I could see faint bluing in a few places on the stem where a slud had feasted on a few of them., other did not have any bluing. I keyed it out 3 times but I was not happy with the results.

These look identical to the species I find in the mixed pitch pine & oak woods in the NJ Pine Barrens, but most of these things look practically the same with a few minor variations. What about the staining of the context — was there a gradual change from pinkish to dark violaceous/blackish? Did you save these?
