I forgot to comment that in 20 years I’ve never found B.mirabilis in the northeast. I’m not saying it doesn’t occur here but I’ve never found it.

agree on chrysenteroides

As Darvin noted the confusion among this group (chrysenteron, chrysenteroides, truncatus)can be cleared up be looking at the spores. I suspect that there may be some confusion about the decayed wood habitat between chrysenteroides and truncatus. Whenever I’ve looked at one of this groups spores that was found on wood it’sbeen chrysenteroides w/bean shaped spores with longitudinal ridges. Admitedly though I haven’t looked at too many examples. It may well be that truncatus also occurs on decayed wood?

did a a bit of research on this looking up B. truncatus and that led me to Boletellus chrysenteroides. It also grows on wood, particularly, well decayed wood of Eastern Hemlock. Quickly stains blue when bruised. The Chemical test seem to match. i have to go with this new name.

Another one that sometimes fruits off of wood is Boletus truncatus. If you have scope, it is easy to ID based on the spores.

maybe not

from my understanding and im not a Boletacea authority but B. Mirabilis is the only bolete that grows on wood. IT was found on a log of Eastern Hemlock but if anyone has any suggestion please feel free.

Not B. mirabilis

Boletus mirabilis does not stain when bruised, in the flesh or the pores.
