Remember the “sensibilis” at NEMF last year, that were like it in almost every aspect but just not right… And when you cut them half the, they had bright yellow stipe flesh. I remember discussing them with you, Roy, Alan and Walt. I now think that this is that species; the unnamed sensibilis.

I think Shroomydan has some pictures of fresh ones on this site, I’ll see if I can find them.

Looks like a lot of red in the stipe….

…for B. sensibilis. I sometimes see some red on the lower third of the stipe in sensibilis but this has a lot.

Has there been any definitive DNA work done on B. sensibilis?

was quick, but for as long as I checked, it was completely bland. Nothing but fungal context without much character. Blue stain never really developed except in the inverted triangle on the upper portion of the stipe and line where the cap context and pore layer touch. Blue on cap context perhaps a bit brighter than in photos, but nothing like the distinct sky blue sometimes seen.

Tapering on stipe is more pronounced in the one sliced. The two others were older and did not have this distinct taper. As the tree was in an arboretum, I do not know the species, but it was not one normally found in NA. Maybe this is a hybrid between something imported and something local.
