Interesting bolete

This looks exactly like the curious bolete I found in Ohio’s Cuyahoga Valley National Park in June of last year growing with oaks and other hardwoods. How do I know it? The stipe readily stains purple vinaceous color upon handling (see pic #3 and compare it with #1), which appears to be a unique and defining characteristic [should be an easy one for Walter Sturgeon :-)]. Other phenotypical charasteristics are a match, too, including brownish reticulation on the similarly colored stipe. I have never found anything like it here in NJ and south-eastern PA. Subtracting the staining action and the ammonia test, it may be related to B. variipes or B. atkinsonii.
