of L. rubropunctum is much different than the Leccinum species I typically find. Looking at photos of the (alleged) species on the internet, this seems like a very good proposal.

Is Boletus ferrugineus the same as Xerocomus ferrugineus? I just proposed X. ferrugineus for one of my own obses. From what I have gathered, I think these are different, with B. ferrugineus having a reticulate stipe.

Not to be confused, of course, with Tylopilus ferrugineus :-)

… and coloration is interesting. I’ve seen something like this in old, waterlogged L. rubropunctum. Xerocomus is evoked no doubt by the pore surface. However, I would expect more ridges for X. illudens and B. ferrugineus (formerly B. spadiceus). Darn, I hope I got those species/genera right. This might be too much for Patrick H.
