Is blue staining.

Thanks for looking at these photos!

B. subvelutipes group…

… is pretty much a “dust bin” to accommodate a confusing phenotypic array of red-pored boletes united by some common but rather variable morphological traits in eastern NA. How many species are out there and which genera they belong to is yet to be determined. An early sequencing foray into sampling this variety showed that nrLSU is not the most informative locus at the species level. However, it did indicate that red-pored entities in the eastern/northeast USA are definitely different from their European and western NA counterparts.

It’s difficult…

to argue one way or the other that this (or any of a multitude of other examples of similarly colored red-pored boletes) represents B. subvelutipes. A key field trait is supposed to be the red/scarlet/yellow velvety tomentum found on the stipe base. In my area (NE PA) what I call subvelutipes is almost always found under conifers. Not very far west of here, deciduous forests seem to be the most common habitat. Michael Kuo does not even mention any conifers in his ME account.

What is the green blotch on the stipe (5th photo from the top)? Is this a chemical reaction?

I. G. Safonov has submitted some similar examples (from NE NA) for sequencing, and he has posted some results here on MO. For example, obs 242312.
