For several reasons that I will go into, I have doubts that this is a species of Boletus. Unfortunately I have no recent literature on the order Boletales, for the group as as a whole I'm looking back to Singer (1986) and there has been a lot of molecular DNA work over the intervening decades resulting in the recognition of many new genera in this order. The type species for Boletus is Boletus edulis described in 1782, it is ectomycorrhizal and I suspect the species that remain in this genus are also ectomycorrhizal. From what I can make of the images the fungus growing is out of solid looking wood (living? or dead?) suggesting it is likely to be lignicolous and either parasitic or saprophytic and hence unlikely to be Boletus sensu stricto. There are other genera in the Boletales that have saprophytic or parasitic species. Another possible issue is that the image showing the underside of the fungus appears to show the hymenial pores extending all the way down the stipe with no clear delineation between hymenium and stipe. Not a character of Boletus and atypical of the few small pored Boletale genera I am familiar with. This may just be my eyes which are not working well at computer screen distances where things keep drifting in and out of focus.

Agree with Ken. Not like even any Boletales I'm familiar with....not to say there arn't things out there I'm not aware of. I'd be tending to think it might be some sort of polypore. Though the colours are interesting! It would be great if a specimen could be collected and looked at microscopically and possibly some DNA work done on it!!?

Interesting. I’ve added a nearby specimen that has a different cap form. Sighting 4569120.

This sighting (4547340) was very near ground level on living wood (though there may have been decay present).
