I’m not sure if it has been sequenced.

It doesn’t occur up in New England as far as I know. I have seen it in eastern PA, OH and SC.

There are a few observations that people have posted on here;
this benign one of them.

thanks for tuning in. Has anyone sequenced this thing? Shall we call it pseudobicolor? :)

This is a somewhat common,

and apparently undescribed species. It has blue staining, pale yellow cap flesh, and bright yellow, non-staining stipe flesh. The odor is similar to sensibilis, but the overall look is more like bicolor.

New bolete book next year?!

I haven’t heard anything about it. What’s your information?

In all honesty, I don’t know what to call your bolete. However, I still think it’s closer to bicolor than sensibilis just by looking at the gross morphology. Dave W posted at few obs of what looks like textbook bicolor with bluing caps, and I feel that your mushroom is the same species.
I went back and re-read Kuo’s bicolor page. What can I say? We can all guess at and argue about the variable odor, bluing pattern, reticulation, coloration, etc., stretching the original species concept or being inflexible about deviating from it, but without doing some real science, i.e. getting DNA sequences from a wide sampling of vouchered collections from different parts of the county, this matter will never be settled to anyone’s satisfaction. The same applies to the red-pored bluing boletes. If I had the money and training to do this kind of work, I would be doing it now….

As usual your observation skills are right on. But what to call it? Maybe when the new bolete book comes out next year we can get some clarification. Have you read Kuo’s comments on Boletus bicolor on Mushroomexpert.com?

Apart from the vigorous bluing on the outside, this mushroom has all the hallmarks of something close to B. bicolor. For instance, look at the tube layer — it’s razor-thin. That’s uncommon for B. sensibilis at this stage of development. I would also expect it to have much less red on the stipe. Lack of bluing on stipe context is also out of character for the “sensitive bolete”. What do you think?
